    1. Ruthenium Cages

      Arene Ruthenium Cages: Boxes Full of Surprises (pages 2445–2453)

      Article first published online: 11 MAY 2009 | DOI: 10.1002/ejic.200900180

      Self-assembly of arene ruthenium building blocks has allowed the construction of cationic metalla complexes of different architectures and functionalities. They show host–guest properties, perform photochemical [2+2] cycloadditions, encapsulate molecules and possess biological activities. This microreview covers synthetic and structural aspects of these metalla-cages as well as their most promising applications.

    1. Ge Clathrates

      Synthesis of the Clathrate-II K8.6(4)Ge136 by Oxidation of K4Ge9 in an Ionic Liquid (pages 2455–2458)

      Arnold M. Guloy, Zhongjia Tang, Reiner Ramlau, Bodo Böhme, Michael Baitinger and Yuri Grin

      Article first published online: 4 MAY 2009 | DOI: 10.1002/ejic.200801073

      Thumbnail image of graphical abstract

      A new metastable binary compound, K8.6(4)Ge136, crystallizing in the clathrate-II structure, was synthesized by the oxidation of K4Ge9 by an ionic liquid.

    2. Porphyrin–Polyoxometalate Complexes

      Ternary Porphyrinato HfIV and ZrIV Polyoxometalate Complexes (pages 2459–2466)

      Alexander Falber, Benjamin P. Burton-Pye, Ivana Radivojevic, Louis Todaro, Raihan Saleh, Lynn C. Francesconi and Charles Michael Drain

      Article first published online: 7 MAY 2009 | DOI: 10.1002/ejic.200900284

      Thumbnail image of graphical abstract

      Porphyrins and polyoxometalates are widely studied molecules because of their tunable physical and chemical properties. A ternary complex is formed when HfIV or ZrIV metal ions coordinate both a porphyrin and a lacunary defect in a polyoxometalate. A crystal structure of a HfIV complex and spectroscopic data suggest that HfIV or ZrIV porphyrins can bind to oxide surfaces by the protruding metal ion.

    3. Templated Synthesis

      Templated Synthesis and Site-Selective Conversion of Completely Nonsymmetrical Bis-Metallosalphen Complexes (pages 2467–2471)

      Ana M. Castilla, Simona Curreli, Nina M. Carretero, Eduardo C. Escudero-Adán, Jordi Benet-Buchholz and Arjan W. Kleij

      Article first published online: 7 MAY 2009 | DOI: 10.1002/ejic.200900282

      Thumbnail image of graphical abstract

      A templated approach toward fully nonsymmetrical bis-metallo(salphen) complexes is described. The dinuclear species can be selectively and stepwise built from useful monometallic triimine precursors. In one case, the presence of different peripheral substituents in both metallosalen units allowed for different reactivity behaviour and site-selective conversion.

    4. Actinide Coordination Chemistry

      A New 5,5′-Bitetrazole Thorium(IV) Compound: Synthesis, Crystal Structure and Quantum Chemical Investigation (pages 2472–2476)

      Roland W. H. Pohl, Jonas Wiebke, Axel Klein, Michael Dolg and Nicola Maggiarosa

      Article first published online: 7 MAY 2009 | DOI: 10.1002/ejic.200900152

      Thumbnail image of graphical abstract

      The novel thorium(IV)(BT)2 hydrate (BT2– = 5,5′-Bitetrazolate) exhibits a salt-like structure (XRD). Density functional (DFT) calculations on gas-phase molecular clusters, employing a relativistic large-core pseudopotential and a large valence-only (7s7p5d2f1g)/[6s5p4d2f1g] basis set for ThIV, confirm the identification of [(μ-OH)2Th2(H2O)14]6+ as the cation in thorium(IV)(BT)2 hydrate.

      Ja Young Park, Eun Sook Choi, Myung Ju Baek, Gang Ho Lee, Seungtae Woo and Yongmin Chang

      Article first published online: 29 APR 2009 | DOI: 10.1002/ejic.200900173

      Thumbnail image of graphical abstract

      A one-pot synthesis for water-solubleligand-coated ultra small paramagnetic or superparamagnetic metal oxide nanoparticles is developed and used in molecular MRI. The iron oxide, manganese oxide, and gadolinium oxide nanoparticles arecoated with hydrophilic and biocompatible ligands. The ligand-coated ultra small gadolinium oxide nanoparticles are superior candidates as T1 MRI contrastagents.

    6. Coordination Polymers

      Activator-Controlled High Temperature In-Situ Ligand Synthesis for the Formation of Rare Earth Thiolate Amide Coordination Polymers (pages 2482–2486)

      Alexander Zurawski, Eva Wirnhier and Klaus Müller-Buschbaum

      Article first published online: 5 MAY 2009 | DOI: 10.1002/ejic.200900208

      Thumbnail image of graphical abstract

      Activator-controlled in situ ligand syntheses by C–S bond cleavage are used for the formation of thiolate amide coordination polymers. Hg functions both as activator for lanthanide metals in the reactionwith 2-mercaptobenzimidazole and promotes the C–S bond cleavage with formation of 2,2′-bibenzimidazole. The reaction path leading to different products can be controlled by the amount of mercury.

    1. Metal Carbonyl Clusters

      Hetero-Bimetallic Ni-Rh Carbido Carbonyl Clusters: Synthesis, Structure and 13C NMR of [Ni10Rh2C(CO)20]2–, [Ni9Rh3C(CO)20]3– and [Ni6Rh8(C2)2(CO)24]4– (pages 2487–2495)

      Cristina Femoni, Maria Carmela Iapalucci, Giuliano Longoni and Stefano Zacchini

      Article first published online: 24 MAR 2009 | DOI: 10.1002/ejic.200900039

      Thumbnail image of graphical abstract

      The new hetero-bimetallic [Ni10Rh2C(CO)20]2– and [Ni9Rh3C(CO)20]3– clusters were prepared by reacting [Ni9C(CO)17]2– with [Rh(cod)Cl]2. Degradation leads to the bis-acetylide [Ni6Rh8(C2)2(CO)24]4–. 13C NMR studies indicate that coordination of Rh atoms to the interstitial carbide is very effective in shortening its longitudinal relaxation time compared to homometallic Ni carbido clusters.

    2. Chromogenic Sensor

      Indirect detection of the 103Rh NMR spectra of a bis(phosphane)RhIII–porphyrin derivative, [Rh(TPP)(PEtPh2)2]SbF6, by polarisation transfer from 31P afforded 103Rh chemical shifts in the range δ = 2480–2590 ppm from 213 to 333 K. DFT simulations at the PBE1PBE/3-21G** level of theory were used to determine stable invacuo structures and shielding tensors (GAIO method) for the complex.

      The new (thianthrene)gold(III) complex salt [AuCl2(TA)2][AuCl4], synthesized in liquid SO2, has a black appearance, an ionic structure and is a semiconductor with low activation energy. If dissolved in chloroform, the ions are converted to an isomeric form built of discrete complexes of [AuCl3(TA)] indicating a solvent-dependent equilibrium.

    6. Polyoxometalates

      The complexes XM(μ-dppm)2M′X react with 1,2-bis(2-isocyanophenoxy)ethanes (diNC) in a 1:1 molar ratio to give the corresponding polymers {[{M(μ-dppm)2M′X}(diNC)]X}n. These polymers are luminescent in solution at 77 K, showing strong luminescence bands in the range 500–800 nm with lifetimes of between 0.2 and 5.6 μs.

      The coordinatively and electronically unsaturated transition-metal complexes (1,8-Ph2-3,6-Me2C12H4N)2M (M = Cr–Co) have been synthesised and the solid-state structures of the manganese and iron systems determined. Solid-state magnetic measurements reveal high spin metal centres which are confirmed by computational calculations for the model complexes M(1,8-Ph2C12H6N)2 (M = Cr–Co).

    9. Azo Complexes

      Article first published online: 8 APR 2009 | DOI: 10.1002/ejic.200900007

      Thumbnail image of graphical abstract

      Reduction of the structurally characterized complexes [PdCl2(pap)], [PtCl2(pap)], and [(az)Pd(μ-Cl)2Pd(az)] leads to radical intermediates where the spin is predominantlylocated on the azo part of the complexes. The radical anion [PtCl2(pap)]· shows unusually large 195Pt hyperfine coupling and g anisotropy for this type of complex.
