      The chemistry of both terminal and bridging (phosphanido)platinum complexes has been surveyed. The structural properties, NMR spectroscopic features and reactivity of the various classes of compounds have been highlighted. Phosphanido-bridged dinuclear complexes are subdivided into PtI compounds, hydrido complexes, halido and aryl or alkyl complexes.

      Spin Canting in a Cobalt(II) Radical Complex with an Acentric Counter Anion (pages 4851–4855)

      Kiyotaka Mitsumoto, Takuya Shiga, Motohiro Nakano, Masayuki Nihei, Hiroyuki Nishikawa and Hiroki Oshio

      Article first published online: 7 OCT 2008 | DOI: 10.1002/ejic.200800824

      The complex cation [CoCl(bisimpy)(MeOH)2]+, where bisimpy is an iminonitroxyl diradical with a triplet ground state, crystallizes in the centric (P21/c) and the polar (Pna21) space groups, respectively,with PF6 and ClO4 anions. The PF6 salt is paramagnetic down to 1.8 K, whereas the ClO4 salt shows a weak ferromagnetic long-range order with a metamagnetic behavior below 2.7 K.

      Ultrafast Vibronic Processes in a Ru–Porphyrin Complex (pages 4856–4860)

      Izumi Iwakura, Atsushi Yabushita and Takayoshi Kobayashi

      Article first published online: 25 SEP 2008 | DOI: 10.1002/ejic.200800532

      Analysis of the six-coordinate complexes of RuII(TPP)(CO)(acetone) (TPP = tetraphenylporphyrin) by using a sub-5-fs pulse revealed that 1Qx(π,π*) had a lifetime of 140 ± 20 fs and the lifetime of 3(d,π*) was560 ± 150 fs. Stimulated emission due to a spin-forbidden transition from 3(π,π*) to the ground state was observed for the first time.

    3. Crystal Engineering

      Synthesis, Structure, and Solvent-Induced Spontaneous Homochiral Assembly of Bidentate Bis(N,N′-diaryl-N-heterocyclic carbene)-Palladium Complexes (pages 4861–4865)

      Takeshi Makino, Hyuma Masu, Kosuke Katagiri, Ryu Yamasaki, Isao Azumaya and Shinichi Saito

      Article first published online: 30 SEP 2008 | DOI: 10.1002/ejic.200800831

      Thumbnail image of graphical abstract

      We synthesized a series of new bidentate bis(NHC)-Pd complexes with xanthene skeleton. The complexes crystallized in twisted conformations and therefore were chiral at solid state. Homochiral crystalswere obtained when cyclic ether was used as the solvent. X-ray analyses indicated that the interaction between the complex and the solvent contributed to formation of the homochiral crystals.

    4. Intra-C–C Coupling at Ruthenium

      Denial of Tris(C,N-cyclometalated) Ruthenacycle: Nine-Membered η6-N,N-trans or η2-N,N-cis RuII Chelates of 2,2′-Bis(2-pyridinyl)-1,1′-biphenyl (pages 4866–4869)

      Omar Saavedra-Díaz, Ricardo Cerón-Camacho, Simon Hernández, Alexander D. Ryabov and Ronan Le Lagadec

      Article first published online: 30 SEP 2008 | DOI: 10.1002/ejic.200800584

      Thumbnail image of graphical abstract

      The reaction between [Ru(η6-C6H6)(phpy)Cl] and Hg(phpy)2 in methanol, where phpy = 2-(2-pyridinyl)phenyl, leads to the unexpected octahedral [RuII(phpy)(pbp)]PF6 complex {pbp = 2,2′-bis(2-pyridinyl)-1,1′-biphenyl}; pbp forms a nine-membered chelate providing η6-tetradentate N/η2-C=C/η2-C=C/N coordination. The C=C units are weakly bound to the RuII center and are readily replaced by CO.

    5. Supramolecular Chemistry

      Unexpected Differences in the Coordination Behaviour of 1,2,4-Triphosphaferrocenes towards CuI Chloride (pages 4870–4874)

      Shining Deng, Christoph Schwarzmaier, Ulf Vogel, Manfred Zabel, John F. Nixon and Manfred Scheer

      Article first published online: 25 SEP 2008 | DOI: 10.1002/ejic.200800852

      Thumbnail image of graphical abstract

      The coordination behaviour of 1,2,4-triphosphaferrocenes towards CuI chloride is decisively influenced by the substitution pattern of the Cp ring attached to iron. For the Cp-substituted derivative a dimeric complex is obtained. In the case of a tri-tBu-substituted Cp″′ ligand complex, the triphosphole is fragmented and rearranges into a tetraphosphabutadiene moiety in an iron triple-decker sandwich complex embedded in a CuCl polymer matrix.

    6. Trifluorovinylferrocene

      Isomeric Al2R4, Mg2R2 Species and Oligomerisation Products: Investigation of Al–Al and Mg–Mg σ Bonding (pages 4879–4890)

      Tobias Pankewitz, Wim Klopper, Patrick Henke and Hansgeorg Schnöckel

      Article first published online: 17 SEP 2008 | DOI: 10.1002/ejic.200800626

      Thumbnail image of graphical abstract

      From recent results for compounds that contain metal–metal σ bonds (Mg–Mg, Zn–Zn, Al–Al) and are stable at room temperature, the question arises whether there are diradical intermediates resulting from·MgR, ·AlR or ·ZnR. Calculations on this subject as well as on oligomeric (AlR2)x and (MgCl)x species show that the synthesis of the metastable solid MgCl, for example, may be possible.

      Article first published online: 16 SEP 2008 | DOI: 10.1002/ejic.200800420

      Thumbnail image of graphical abstract

      The magnetic and photomagnetic properties of two new spin-crossover complexes with N4O2 coordination are presented. From the data for six spin-crossover complexes, an initial explanation was given with regard to which parameters are responsible for the extent of intermolecular interactions in this type of complex.

      Thumbnail image of graphical abstract

      Three novel polyoxometalate anions, V9TeO285– (I), V3Mo3O249– (III), and V5Mo3TeO275– (IV), have been observed, in addition to TeMo6O246– (II), in aqueous MoVI-VV-TeVI solutions in the pH range 8–1, by using 51V, 95Mo, 17O, and 125Te NMR spectroscopy. Upon adding Nb oxalate, the Mo and V oxalates also form.

      Article first published online: 25 SEP 2008 | DOI: 10.1002/ejic.200800214

      Thumbnail image of graphical abstract

      Reaction of ZrOCl2 with A-α-[SiW9O34]9– leads to a “sandwich” complex which consists of a central triangular {Zr3O3} core closely embedded between two {SiW9O34} subunits. Structural characterisation shows that the central {Zr3O3} core becomes protonated as a result of a remarkably slow proton transfer within the central triangle.

      The synthesis and characterisation (X-ray, FTIR, UV/Vis, emission spectroscopy, electrochemistry) of sulfate-bridged dimeric copper(II) complexes with a 3D network using N-heterocyclic ligands are reported. Electrochemistry shows metal-centred oxidation in both cases. DFT and TDDFT calculations provide useful information on the electronic structures and spectroscopic transitions of the complexes.

      Thumbnail image of graphical abstract

      Demonstration of photoreversible zinc ion transportation across an organic/aqueous interface using indolospiropyrans is reported. Biasing of the photodynamic equilibrium, and consequently zinc ion transportation, is further controlled using strategically placed, sterically, and electronically influencing substitutents.

    11. Isotopic Exchange Reactions

      16O/18O exchange reactions of gaseous vanadium oxide cluster cations with oxygen-labeled water and molecular oxygen were probed by mass spectrometry. Degenerate 16O/18O exchange with water is primarily obtained for the VmOn+ cluster cations with a medium valence state of vanadium, whereas V3O6+ and V4O8+ are the only cluster cations to activate O2.

      Thumbnail image of graphical abstract

      Unique binding mode: A series of bimetallic complexes is synthesized, in which the configuration around the two palladium centers can be cis-cis, trans-trans, or even trans-cis, although both centers are surrounded by the same ligands. The coordination mode can be tuned by variation of the steric bulk of the ligands.
