      The reaction of stanna-closo-dodecaborate with [(dppm)NiBr2] and [(dppe)NiBr2]resulted in the formation of trigonal-bipyramidal compounds [(dppm)Ni(SnB11H11)3]4– and [(dppe)Ni(SnB11H11)3]4–, respectively, which exhibit fluxional behavior in solution. Furthermore, the reaction of stannaborate with [(ImiPr2Me2)2NiBr2]yielded the nonfluxional square-planar coordination compound [(ImiPr2Me2)2Ni(SnB11H11)2]2–.

    1. Reactions of Pendant Boryl Groups in Cp–Metal Complexes: Heterocyclic Ring Annelation in a CpIr System (pages 2273–2277)

      Christoph Herrmann, Gerald Kehr, Roland Fröhlich and Gerhard Erker

      Version of Record online: 29 FEB 2008 | DOI: 10.1002/ejic.200701166

      η5-(1-Propenyl-C5H4)(cod)Ir reacts with HB(C6F5)2 presumably by means of asequence involving regioselective hydroboration, followed by an intramolecular electrophilic substitution reaction at its Cp ring system, to eventually yield an iridium hydride product that exhibits an annelated five-membered boron heterocycle.

    2. Synthesis, X-ray Structure and Reactivity of a Sterically Protected Azobisphenol Ligand: On the Quest for New Multifunctional Active Ligands (pages 2278–2285)

      Emi Evangelio, Javier Saiz-Poseu, Daniel Maspoch, Klaus Wurst, Felix Busque and Daniel Ruiz-Molina

      Version of Record online: 4 APR 2008 | DOI: 10.1002/ejic.200701339

      Thumbnail image of graphical abstract

      Different synthetic routes have been explored for the synthesis of the sterically protected azobisphenol ligand. Moreover, its complexation ability, together with the reversible deprotonation of the phenol groups, has used to create a chromophoric array of three states with significantly different colours, which can interconvert reversibly between them.

    3. Crystal Structure and Magnetism of the 6H Hexagonal Double Perovskites Ba2FeSbO6 and Ba2CoSbO6–δ: A Neutron Diffraction and Mössbauer Spectroscopy Study (pages 2286–2294)

      M. Retuerto, J. A. Alonso, M. J. Martínez-Lope, M. García-Hernández, K. Krezhov, I. Spirov, T. Ruskov and M. T. Fernández-Díaz

      Version of Record online: 4 APR 2008 | DOI: 10.1002/ejic.200800055

      The crystal structure of the title perovskites can be defined as a 6-layered (6H) hexagonal perovskite structure (space group P63/mmc) containing dimer units of (M,Sb)O6 octahedra sharing a face along the c axis. The Fe compound shows a severe antisite disordering, whereas the Co perovskite, containing Co2+, is O-deficient, which reduces the disordering. No long-range magnetic ordering was found.

    4. Bis- and Tris(tetraazamacrocyclic) Copper Complexes with Disulfide Linkers (pages 2295–2301)

      Monika Galińska, Bohdan Korybut-Daszkiewicz, Urszula E. Wawrzyniak, Renata Bilewicz, Pawel Śledź, Radosław Kamiński, Paulina Dominiak and Krzysztof Woźniak

      Version of Record online: 4 APR 2008 | DOI: 10.1002/ejic.200701231

      Thumbnail image of graphical abstract

      Di- and trinuclear complexes containing two and three macrocyclic fragments bound by aliphatic linkers with the -S–S- built-in units self-assemble at gold surfaces to produce stable monolayer-modified electrodes. The immobilization of these highly charged cations on the electrode required the application of appropriate negative potential during the self-assembly process.

    5. A Study on the Coordinative Versatility of the Zwitterionic S,N,S Ligand EtNHC(S)­Ph2P=NPPh2C(S)NEt in Its Anionic, Neutral and Cationic Forms – Determination of Absolute pKa Values in CH2Cl2 of RhI Complexes (pages 2302–2312)

      Massimiliano Delferro, Daniele Cauzzi, Roberto Pattacini, Matteo Tegoni, Claudia Graiff and Antonio Tiripicchio

      Version of Record online: 4 APR 2008 | DOI: 10.1002/ejic.200800075

      Thumbnail image of graphical abstract

      The zwitterionic ligand EtNHC(S)Ph2P=NPPh2C(S)NEt (HEtSNS) is amphoteric. Its three forms, zwitterionic (HEtSNS), zwitterionic–anionic (EtSNS), and cationic (H2EtSNS+), show coordinatingproperties towards RhI species. The [Rh(CO)EtSNS] complex behaves as a biprotic base, and its absolute acid constants (pKa) were determined in dichloromethane.

    6. Synthesis and Reactivity of Oxametallacyclic Niobium Compounds by Using α,β-Unsaturated Carbonyl Ligands (pages 2313–2320)

      Rocío A. Arteaga-Müller, Javier Sánchez-Nieves, Pascual Royo and Marta E. G. Mosquera

      Version of Record online: 4 APR 2008 | DOI: 10.1002/ejic.200800060

      Thumbnail image of graphical abstract

      Mono(cyclopentadienyl)niobium compounds [NbCpRCl2(LL)] with α,β-unsaturated carbonyl ligands (LL = MMA, MA, MO) have been synthesized, and their reactions with Brönsted (TfOH) and Lewisacids [E(C6F5)3] (E = B, Al) and with CO and CNAr have been studied.

    7. Salts with the Triborate Anion [B3O3F2(OH)2]: A Combined Experimental and Theoretical Study (pages 2321–2325)

      Maik Finze and Guido J. Reiss

      Version of Record online: 1 APR 2008 | DOI: 10.1002/ejic.200800068

      Thumbnail image of graphical abstract

      The [B3O3F2(OH)2] anion was obtained from reaction mixtures of [3-NC-B11F10]2– with aqueous KOH. [Ph4P][B3O3F2(OH)2] and [Ph3MeP][B3O3F2(OH)2] were isolated as colorless crystals. The anions form infinite hydrogen-bonded chains in the solid state. In [Ph4P][B3O3F2(OH)2] these chains are flat and in the [Ph3MeP]+ salt they are twisted.

    8. Coordination Studies of a New Nonsymmetric Ditertiary Phosphane Bearing a Single Phosphaadamantane Cage (pages 2326–2335)

      Tom J. Cunningham, Mark R. J. Elsegood, Paul F. Kelly, Martin B. Smith and Paul M. Staniland

      Version of Record online: 2 APR 2008 | DOI: 10.1002/ejic.200800059

      A new nonsymmetric ditertiary phosphane, Ph2PCH2CH2PAd, is reported along with a study of the coordination chemistry of this ligand with a range of late transition metal precursors. Various bonding modes have been established (monodentate, chelate, bridging) and verified by a combination of spectroscopic (multinuclear NMR, FT-IR) and X-ray crystallographic techniques.

    9. Syntheses, Structures and Photophysical Properties of New Heterodinuclear Cd–Ln Coordination Complexes (Ln = Sm, Eu, Tb, Nd, Ho, Er) (pages 2336–2343)

      Yu-Xian Chi, Shu-Yun Niu, Zhao-Long Wang and Jing Jin

      Version of Record online: 2 APR 2008 | DOI: 10.1002/ejic.200800106

      Thumbnail image of graphical abstract

      Six heterodinuclear Cd–Ln complexes (Ln = Sm, Eu, Tb, Nd, Ho, Er) were hydrothermally synthesized and characterized. These Cd–Ln complexes are difficult to synthesize because of the high coordination ability of cadmium(II) and are rarely reported. Meanwhile, the six complexes show peculiar emission bands in the visible region and in the NIR region because of their heterodinuclear nature.

    10. Silylene and Germylene Intermediates in the Reactions of Silole and Germole Dianions with N,N′-Di-tert-butylethylenediimine (pages 2344–2349)

      Spiro-diazasilole (germole) adducts were observed in reactions of dilithium salts of silole and germole dianions with N,N-di-tert-butylethylenediimine in THF at roomtemperature. Proposed mechanism of the reaction includes metallation of N,N′-di-tert-butylethylenediimine and formation of intermediate silylene and germylene
