      Binary B4S4 Rhombic Clusters as Promising Inorganic Ligands for ­Triple-Decker Sandwich Complexes

      Da-Zhi Li, Shi-Guo Zhang and Chen-Chu Dong

      Article first published online: 5 FEB 2016 | DOI: 10.1002/ejic.201501439

      Thumbnail image of graphical abstract

      The binary B4S4 rhombic cluster possesses a four-membered heteroatomic ring with 4π electrons in a nonbonding/bonding combination, differing from cyclobutadiene. B4S4 (C2v 1A1) is predicted to be an effective inorganic ligand to form triple-decker sandwich-type transition-metal complexes, such as D2h (B4S4)3M2 (M = Ni, Pd, and Pt).

    2. P,N-Heterocycles

      Conformational Analysis of P,N-Containing Eight-Membered Heterocycles and Their Pt/Ni Complexes in Solution

      Shamil Latypov, Anna Strelnik, Anna Balueva, Yulia Spiridonova, Andrey Karasik and Oleg Sinyashin

      Article first published online: 5 FEB 2016 | DOI: 10.1002/ejic.201501331

      Thumbnail image of graphical abstract

      Biligand complexes ([M(PR2NR′2)2]2+, M = Pt, Ni) are in CBCB1 conformation with distortion of the metal coordination plane. Ni complexes have higher distortion and intramolecular exchange barriers than Pt complexes. Bulky P-substituents increase the distortion of the coordination plane and slow down its “twisting” rate. The counterion type also affects the structure and dynamics of these complexes.

      Article first published online: 4 FEB 2016 | DOI: 10.1002/ejic.201501455

      Thumbnail image of graphical abstract

      Sr2Pd4Al5 crystallizes in a new structure type that exhibits an interesting bonding situation within the polyanionic [Pd4Al5]δ framework. DFT calculations confirm the crystallographically observed bonding situations and that the compound should be considered polar intermetallic since Sr transfers its electrons mainly onto the palladium atoms.

      Article first published online: 4 FEB 2016 | DOI: 10.1002/ejic.201501220

      Thumbnail image of graphical abstract

      Small thiol-functionalized oligosilsesquioxanes were prepared by the in situ water production (ISWP) process in which water was homogenously generated by an esterification reaction. Manipulation of the temperature allowed the water production kinetics to be controlled, which played a major role on the degree of condensation (DOC) of the formed nanobuilding blocks.

      Thermoelectric Properties of Ni0.05Mo3Sb5.4Te1.6 with Embedded SiC and Al2O3 Nanoparticles

      Nagaraj Nandihalli, Quansheng Guo, Stéphane Gorsse, Atta Ullah Khan, Takao Mori and Holger Kleinke

      Article first published online: 3 FEB 2016 | DOI: 10.1002/ejic.201501063

      Thumbnail image of graphical abstract

      Nanocomposites of Ni0.05Mo3Sb5.4Te1.6 with embedded SiC and Al2O3 nanoparticles are introduced. The nanoadditions lower the thermal and electrical conductivities to different extents, ultimately resulting in enhanced thermoelectric performance (ZT) on addition of small amounts of SiC. A more substantial enhancement was achievement by spark-plasma-sintering instead of hot-pressing.

      Trimethylplatinum(IV) complexes featuring agostic B–H–Pt interactions supported by bis(pyrazolyl)borate (Bp) and bis(3,5-dimethylpyrazolyl)borate (Bp*) ligands show interesting structural differences both in solution and the solid state. These differences result in enhanced reactivity of the Bp* complexes towards hydroboration of acetonitrile and protonolysis with methanol.

      Thumbnail image of graphical abstract

      Iron(III) catecholates bearing anthracenyl or pyrenyl groups and a dipicolylamine base with a cationic triphenylphosphonium (TPP) moiety show remarkable photocytotoxicity under red light, mitochondrial localization, reactive oxygen species (ROS) generation, and apoptotic cell death. They showed significant DNA photocleavage activity under red light (785 nm), forming hydroxyl radicals as the ROS.

      Activation of Heteroallenes COxS2–x (x = 0–2): Experimental and Theoretical Evidence of the Synthetic Versatility of a Bulky Guanidinato SmII Complex

      Ludovic Castro, David P. Mills, Cameron Jones and Laurent Maron

      Article first published online: 1 FEB 2016 | DOI: 10.1002/ejic.201501346

      Thumbnail image of graphical abstract

      A combined experimental/DFT study of the activation of COxS2–x (x = 0–2) by [Sm(Giso)2] is reported. Activation of CS2 yields a bimetallic CS2 coupled product. CO2 forms an oxalate complex through C–C bond formation, which then undergoes CO2 insertion into one of its Sm–N bonds. COS activation is predicted to yield a dithiocarbonate complex, through the formation of an intermediate sulfido complex.

      The phosphonic bridges in the uranyl cage clusters U22 and U28 have been monitored in aqueous solutions using the unique combination of 1H DOSY and 1H-31P HSQC spectroscopy. The hydrodynamic radii of these clusters are measured to be 9.8 ± 0.4 Å (U22) and 12.3 ± 0.5 Å for the (U28) in D2O. Relating specific sites in the structures of these clusters to NMR signals reveals the presence of phosphonic-bridge conformers.

      Prussian Blue analogue nanoplatelets have been produced by pseudomorphic replication of layered Cu2(OH)3(OAc) in the presence of K4[Fe(CN)6]. A transformation mechanism is proposed. Our results demonstrate that lamellar simple hydroxides can be used as precursors of molecular-based networks and that the lamellar nature of the Cu reservoir favours the organization of crystallites into sheets.

      We report herein the synthesis, XRD characterization, and electrical properties of new lead-containing layered molybdates based on Nd2MoO6. In contrast to pure Nd2MoO6, these materials reveal first-order reversible phase transitions accompanied by dielectric anomalies, DSC events, and sharp jumps in conductivity. The conductivity reaches 10–2 S/cm at 850 °C and may be due to oxygen ions.

      A nanocarrier for loading and releasing ketoprofen combines nanoemulsions with mesostructured silica. The release of the drug is pH responsive. By contrast, for the impregnation of ketoprofen in the bare macro-/mesoporous silica, a micelle-assisted release is observed. The modeling of the release profiles with the Korsmeyer–Peppas equation evidences a pseudo-Fickian release mechanism.

      Mixtures of polyoxyethylene fluoroalkyl ether and triblock copolymer were used to prepare hierarchical porous silica materials. Dual-mesoporous materials were obtained from the coexistence of two types of micelles through the cooperative templating mechanism (CTM), and macro-mesoporous silica materials were templated by concentrated emulsions.

      Aluminium matrix composites with different volume fractions of nonagglomerated nanodiamond reinforcing particles are developed. The uniform distribution of nonagglomerated nano-reinforcements in an aluminium matrix can significantly slow down the recrystallization of the matrix material during heating, which becomes evident only when it is heated above 350 °C.

      Two 2D coordination polymers, [M(ppvppa)2(1,3-bdc)]n (M = Cd, Co), have been synthesized by solvothermal reactions. Immersing them into AgNO3 solution produced two AgI-doped polymers, [Cd(ppvppa)2(1,3-bdc)]·AgNO3 and [Co(ppvppa)2(1,3-bdc)]·0.75AgNO3, which showed greatly enhanced catalytic activity towards the photodegradation of various organic pollutants in water compared with their precursors.

      Homoleptic MnIII complexes of the scorpionate Tp and Tp* ligands are rare examples of low-spin MnIII species. The electronic structures of these species were compared using MCD spectroscopy and CASSCF/NEVPT2 computations. Complementary computations for the related [{Ph(MeIm)3B}2MnIII]+ species, which features an NHC ligand, explain variations in zero-field splitting for these complexes.

      The high temperature magnetic and structural properties of an amphiphilic iron(III) spin crossover complex are reported. Thermal cycling reveals a scan rate-dependent 20 K thermal hysteresis close to room temperature. Differential scanning calorimetry and cross polarized microscopy are used to show that the magnetic switching aligns with a material change from solid to ordered liquid phase on warming.

      Cage-chiral P–C cage compounds are a new class of chiral ligands. A stereoselective rearrangement performed with highly enriched P5-deltacyclene enantiomers is accompanied by a unique cage inversion, which results in almost mirror-symmetric CD curves of related pairs of P5-deltacyclene/iso-P5-deltacyclene enantiomers. The absolute structure of a W(CO)5 complex enantiomer confirms the observation.
