      The cover picture shows the X-ray structure of the first clathrochelatoscorpionate with a macrobicyclic encapsulating ligand that forms a “shell” round the caged iron(II) ion; this “shell” almost completely isolates it from external factors. One of the chelate ribbed fragments of this hybrid molecule contains a pyrazolate donor group that usually gives the so-called “scorpionates” – the tripodal tris(pyrazolate) ligands. The structural similarity of these two types of intensively studied metal complexes (i.e., the clathrochelates and the scorpionates) was used to design hybrid complexes that are described in the Short Communication by O. A. Varzatskii, Y. Z. Voloshin et al. on p. 1987 ff.

      The first hybrid clathrochelatoscorpionate and its pyrazoloxime-armed macrocyclic intermediate were obtained by cycloaddition of a new pyrazoloxime to macrocyclic iron(II) bis(α-benzyldioximate) and characterized by X-ray crystallography, spectroscopy, and cyclic voltammetry.

    2. Lithium Amide Nanoparticles

      Synthesis of Pure Lithium Amide Nanoparticles (pages 1993–1996)

      Gael Baldissin, Neil M. Boag, Chiu C. Tang and Daniel J. Bull

      Version of Record online: 8 MAR 2013 | DOI: 10.1002/ejic.201201535

      Thumbnail image of graphical abstract

      Pure lithium amide can be synthesised efficiently by deprotonation of ammonia with n-butyl lithium. In comparison to commercial samples, the lithium amide produced is a pure, free-flowing powder that quantitatively generates lithium imide at 600 K. The methodology readily affords the production of pure lithium amide and imide and their deuterated analogues at both bench-top and commercial scale.

    3. Dichotomy in Pd–Sn Complexes

      Dichotomy between Palladium(II)–Tin(II) and Palladium(0)–Tin(IV) in Complexes of a Sn,As-Based Chelate Ligand (pages 1997–2001)

      Thumbnail image of graphical abstract

      Metal oxidation states in Pd–Sn compounds are a continuing puzzle. A novel dinuclear Pd–Sn bonded complex is reported, in which the interaction of the formally tin(II)-based ligand, [2-MeBrSnC6F4AsPh2], with palladium appears to be best described as PdI–SnIII or Pd0–SnIV.

    4. Metal Clusters

      A Missing Link in Undecagold Cluster Chemistry: Single-Crystal X-ray Analysis of [Au11(PPh3)7Cl3] (pages 2002–2006)

      Version of Record online: 19 MAR 2013 | DOI: 10.1002/ejic.201300148

      Thumbnail image of graphical abstract

      Got you! Since 1966, reduction of [Au(PPh3)Cl] in ethanol represented the easiest large-scale synthesis of undecagold and gold clusters. However, the full molecular structure of this Au11 cluster remained unclear, and several formulae were published. Now, structure elucidation was successful, which is thought to bring added value from past publications and important impact to new investigations.

      Version of Record online: 11 FEB 2013 | DOI: 10.1002/ejic.201201471

      Thumbnail image of graphical abstract

      The sterically induced formation of phosphanyl radicals is the crucial step that determines if magnesium reduction of N-heterocyclic chlorophosphanes in the presence of Et3NHCl gives diphosphanes or proceeds all the way to yield secondary phosphanes. The latter can be converted back to diphosphanes upon exposure to light.

    5. Phosphorus Activation at Nickel

      The reaction of [Ni2(iPr2Im)4(cod)] (1) with white phosphorus leads to dinuclear [{Ni(iPr2Im)2}2(μ,η2:2-P2)] (2) in excellent yield. DFT calculations on symmetrized model complexes of 2 revealed that the deviation of the Ni2P2 core from planarity is caused by a second-order Jahn–Teller distortion.

      The water-exchange mechanism of [Zn(H2O)4L]2+·2H2O (L = O-donor ligands) has been studied by DFT calculations (B3LYP/6-311+G**). The calculated energy values and structural data provide theoretical evidence that the water-exchange process follows an associative reaction mechanism that involves two reaction steps and the formation of a six-coordinate intermediate [Zn(H2O)5L]2+·H2O.

    7. Metallametallocenes

      The lowest-energy structures for CpM(C4H4M)Cp (M = Fe, Co, or Ni) are triplet-, singlet-, and triplet-spin-state structures, respectively, with formal metal–metal single bonds for the Fe and Co derivatives and no significant Ni···Ni interaction for the Ni derivative. The lowest-energy structures for the heterometallic derivatives CpM(C4H4M′)Cp (M, M′ = Fe, Co, or Ni) are always the lowest-spin-state structure with the electron-richest metal atom in the metallacyclic ring.

      New trans-1,2-diphenylethylenediamine-linked salicylaldiminato–isoindoline nickel complexes are active catalysts for ethylene oligomerization and the homopolymerization of norbornene and styrene with methylaluminoxane (MAO) as cocatalyst. Dehydrogenation of the chelated tridentate ligand takes place and the two bridged benzylic carbon atoms are oxidized to form a cis-stilbene moiety.

      Copper sulfide microflowers, free from any type of organic impurities, have been synthesized by the hexamethyldisilazane-assisted method. The flowers were constructed by the intricate self-assembly of flake-like architectures. The flakes have widths of 12.6 ± 3.4 nm and their lengths vary. The wide distribution of flake lengths directly influenced the sizes of the flowers (100 nm to 3 μm).

Spin-conversion equilibria (T1/2) of 330 and 320 K were found for 1 and 2, respectively. The spin-crossover behavior is gradual and reversible. A close correlation with the solution spin state and E1/2 is observed.

      Thumbnail image of graphical abstract

      The reactivity of phosphorus–sulfur bis(ylides), ylide–sulfides, and ylide–methanides toward PdII has been studied. Neutral bis(ylides) bond as C,C-chelates diastereoselectively [meso form (RS/SR)] owing to a combination of 1,4-P···O and 1,4-S···O interactions and 1,6-CH···O hydrogen bonds. The anionic ylide–methanide also bonds selectively as a C,C-chelate, but in the D,L form (RR/SS).

      Pyranoside phosphinite-oxazoline ligands were successfully applied in the asymmetric Ir-catalyzed hydrogenation of a wide range of minimally functionalized olefins (ee up to 99 %). The introduction of a bulky ortho-tolyl phosphinite moiety was crucial to achieving the highest enantioselectivities with some of the most challenging substrate types.

      Treatment of (imido)Ti, -V and -Mo dichloride complexes with LiBH4 gives imido bis(borohydride) complexes, which have been studied by NMR and EPR spectroscopy, and X-ray diffraction.

      Five Pt complexes in oriented smectic liquid crystals exhibit polarized luminescence perpendicular to the orientation direction, which is assigned to the monomer and excimer states. The polarization ratios are estimated to be up to 2.9 and 5.4, respectively, in these states, which are higher than those of Pt complex/nematic LC mixtures.

      Metal–metal bonds that consist of Group 12 elements were computationally introduced into three types of hybrid fullerene cages. The structures, stabilities, and bonding situations of these M2@C50X10 (M = Zn, Cd, Hg; X = CH, N, B) complexes were analyzed.

      Trimetallic [{Pt(C6F5)(bzq)L}2Ag]+ and bimetallic [(C6F5)(bzq)(PPh3)PtAg(pyPh2)]+ clusters containing Pt–Ag bonds were prepared from [Pt(C6F5)(bzq)L] (bzq = 7,8-benzoquinolinate). These complexes have luminescent properties that were studied and interpreted with the help of time-dependent DFT calculations.
