      The identification of suitable metal catalysts often translates directly to finding a proper ligand, which is enormously facilitated by the availability of ligand libraries. Bidentate P ligands are an important class the development of which is still challenging. In this review we discuss divergent synthesis, supported synthesis, and self-assembly as strategies to get ligand libraries.

    1. Lanthanide-Hinged Calixarene Bicapsules: Discrete Hexanuclear LnIII/Phenanthroline/p-Sulfonatocalix[4]arene Oligomers (Ln = Gd, Tb) (pages 2959–2962)

      Wuping Liao, Yanfeng Bi, Song Gao, Deqian Li, Hongjie Zhang and Richard Dronskowski

      Version of Record online: 27 MAY 2008 | DOI: 10.1002/ejic.200800297

      Thumbnail image of graphical abstract

      Two novel LnIII–C4AS compounds have been synthesized, which contain the rarely reported LnIII-hinged calixarene bicapsules. The Gd-containing sample exhibits a very weak antiferromagnetic interaction between the Gd3+ ions and the Tb-containing sample shows a characteristic Tb-centered luminescence, which indicates an efficient energy transfer from the calixarene unit to the Tb3+ ion.

    2. Quenching the Hysteresis in Single Crystals of a 1D Chain Iron(II) Spin Crossover Complex (pages 2963–2966)

      Birgit Weber, Eike S. Kaps, Cédric Desplanches and Jean-François Létard

      For a 1D chain iron(II) complex unusual grinding effects are observed. The origin of those effects is investigated using magnetic measurements, X-ray powder diffraction and optical reflectivity studies.

    3. C–C Coupling Reactions of Pentacarbonyl(trifluoroethenyl isocyanide)chromium with Cyclopentadienyl Complexes (pages 2967–2970)

      Dieter Lentz, Monika Mujkic and Stefanie Roth

      Version of Record online: 30 MAY 2008 | DOI: 10.1002/ejic.200800194

      A highly efficient synthesis of fluorinated alkenyl isocyanide complexes with organometallic substituents is described. As long as the lithium organic substance, like for example 1,1′-dilithioferrocene, can be prepared there seems to be no limitations in the utility of this method. In the disubstituted ferrocene derivative the bulky substituents are in an almost eclipsed position.

    4. A Rare Thermally Induced Single Crystal to Single Crystal Transformation from a 2D Chiral Coordination Polymer to a 3D Chiral Coordination Polymer (pages 2971–2974)

      Ping Zhu, Wen Gu, Li-Zhi Zhang, Xin Liu, Jin-Lei Tian and Shi-Ping Yan

      Version of Record online: 28 MAY 2008 | DOI: 10.1002/ejic.200800276

      Photophysical properties and surface structures of silica-gel-supported photofunctional (phthalocyaninato)silicon complexes (SiPc-SiO2) have been investigated. By changing the amount of SiPcs, we have succeeded in preparing solid materials based on Pc complexes having both monomeric photophysical properties and a high ability for singlet-oxygen generation.

    2. Solvent-Mediated Ion Exchange and Structural Transformations of Cluster-Based Coordination Polymers (pages 2982–2990)

      A series of cyclohexane-1,2-diyl linkedbis(ketiminato)aluminum complexes containing cyclohexane-1,2-diyl linked bis(ketiminato) ligands were synthesized, and their subsequent reactions were also studied.

    5. Allylic Amination and Aziridination of Olefins by Aryl Azides Catalyzed by CoII(tpp): A Synthetic and Mechanistic Study (pages 3009–3019)

      Alessandro Caselli, Emma Gallo, Simone Fantauzzi, Simona Morlacchi, Fabio Ragaini and Sergio Cenini

      Version of Record online: 27 MAY 2008 | DOI: 10.1002/ejic.200800156

      Thumbnail image of graphical abstract

      CoII(tpp) catalyzes the reaction of aromatic azides with nonactivated olefins to yield allylic amines or aziridines in moderate-to-good yields. The reaction mechanism was investigated and found to proceed through reversible coordination of the aryl azide to the CoII–porphyrin complex. The often postulated “nitrene” complex is not an intermediate in this reaction.

      The organic–inorganic hybrid materials ZnCl2(AEC)2 (1), ZnI2(AEC)2 (2), CdI2(AEC)2 (3), and HgI2(AEC)2 (4) were synthesized. The crystal structures of CH3CN and CH3CN reveal quasi-1Dinorganic frameworks. The optical energy gaps of these materials are influenced by the AEC ligands; compounds 1, 2, and 3 give deep-blue emissions from the AEC ligands, whereas 4 does not emit light.

    10. Copper(II) Complexes with Bridging Diphosphinates – The Effect of the Elongation of the Aliphatic Chain on the Structural Arrangements Around the Metal Centres (pages 3046–3055)

      Ferdinando Costantino, Andrea Ienco, Stefano Midollini, Annabella Orlandini, Lorenzo Sorace and Alberto Vacca

      The structures of a series of CuII-(2,2′bipy) complexes with two closely related diphosphinates [O2(Ph)P–alkyl–P{Ph(O2)}]2– have been analyzed together with those of the corresponding diphosphinic acids. Thedifferent conformations adopted by the diphosphiante groups as a result of the alkyl chain elongation account for the remarkably different steric arrangements of the corresponding Cu complexes.

    11. Formation of L-Threonic Acid from L-Ascorbic Acid Oxidative Ring Opening and its Coordination to PtII: X-ray Crystal Structures of [Pt(threonato-O,O′)(PPh3)2] and [Pt(oxalato)(PPh3)2] (pages 3056–3061)

      The ring opening induced by atmospheric molecular oxygen in a basic solution ofL-ascorbic acid produced oxalic and L-threonic acid. The reactions of these acids with the carbonate complex [Pt(CO)3(PPh3)2] yielded [Pt(oxalato)(PPh3)2] and the new complex [Pt(threonato-O,O′)(PPh3)2], respectively. The X-ray crystal structures of both complexes were determined.

      Version of Record online: 27 MAY 2008 | DOI: 10.1002/ejic.200800230

      Thumbnail image of graphical abstract

      The ionic fluorides Ag3M2F14 (M = Zr, Hf) react with liquid ammonia. The AgII ions of the starting materials are reduced to AgI, and all coordination polyhedra completely rearrange and form the new fluorideammoniates Ag2MF6·8NH3 (M = Zr, Hf), which feature argentophilic interactions previously unknown in fluorides. The reduction of AgII to AgI and the high solution enthalpy of AgI enable this reaction.
