      This Microreview gives an up-to-date account of the advances made by the author's group and by other groups, in recent years, on spin-crossover compounds of iron(II), iron(III) and cobalt(II) of the dinuclear cluster and 1-D chain types. As well as describing their syntheses, design, structures, magnetism and photomagnetism, a systematic delineation of the kinds and mechanisms of observed spin transitions is presented.

      The reaction of CoII and 2,2′-dipyridyldisulfide (PySSPy) in the presence of azide produced a monomeric complex [CoIII(PyS)(PyS-N-SPy)(N3)] (1), which was characterized by means of UV/Vis, X-ray crystallography, XPS, and cyclic voltammetry. The unusual, N-inserted ligand PyS-N-SPy can be stabilized through coordination to the electropositive CoIII ion.

    1. Structure and Properties of NaBH4·2H2O and NaBH4 (pages 3127–3133)

      Yaroslav Filinchuk and Hans Hagemann

      Article first published online: 19 MAR 2008 | DOI: 10.1002/ejic.200800053

      Thumbnail image of graphical abstract

      NaBH4·2H2O and NaBH4 were studiedby single-crystal X-ray diffraction andvibrational spectroscopy. Nearly ideal tetrahedral BH4 anions are bridged with Na+ ions through the edges. NaBH4·2H2O does not contain classical hydrogen bonds, but reveals strong O–Hδ+···δH–B bonds. At 313–315 K, the structure decomposes into NaBH4 and H2O, which react to form hydrogen gas.

    2. A Dawson-Type Dirhenium(V)-Oxido-Bridged Polyoxotungstate: X-ray Crystal Structure and Hydrogen Evolution from Water Vapor under Visible Light Irradiation (pages 3134–3141)

      The reaction of [α2-P2W17O61]10– with [ReIVCl6]2– in water afforded K14[O{ReV(OH)(α2-P2W17O61)}2]·21H2O (K-1), whose single-crystal X-ray structure analysis revealed overall C2h symmetry. K-1 was grafted onto a TiO2 surface by electrostatic binding to give TiO2 with a cationic quaternaryammonium moiety (1-grafted TiO2), which effected hydrogen evolution from water vapor under visible light irradiation.

    3. Palladacyclic Complexes Containing C,N-Type Ligands as Catalysts in Cross-Coupling Reactions (pages 3142–3150)

      Ming-Tsz Chen, Chi-An Huang and Chi-Tien Chen

      Article first published online: 10 JUN 2008 | DOI: 10.1002/ejic.200800195

      We present the syntheses and the molecular structures of novel palladacycles and theircatalytic activities in Suzuki and Heck reactions.

    4. Synthesis, Structure and Spectroscopic Properties of Lanthanide Complexes of N-Confused Porphyrins (pages 3151–3162)

      Xun-Jin Zhu, Feng-Lei Jiang, Chun-Ting Poon, Wai-Kwok Wong and Wai-Yeung Wong

      Article first published online: 10 JUN 2008 | DOI: 10.1002/ejic.200800267

      Thumbnail image of graphical abstract

      Lanthanide complexes of N-confused porphyrins with different rare-earth metals and phenyl ring substituents are synthesized in which the tripodal cobaltate anion acts as an effective encapsulating agent for Ln3+ and an η2-agostic interaction exists between the metal center and the innerC–H bond of the porphyrinate ligand.

    5. Sol–Gel Synthesis of Tunable Cerium Titanate Materials (pages 3163–3171)

      Mónica Martos, Beatriz Julián-López, José Vicente Folgado, Eloisa Cordoncillo and Purificación Escribano

      Article first published online: 4 JUN 2008 | DOI: 10.1002/ejic.200800303

      Thumbnail image of graphical abstract

      Sol–gel synthesis of cerium titanates with tunable Ce3+/Ce4+ content, crystalline structure and optical properties are reported. XRD, Raman spectroscopy and magnetic measurements corroborate the crystallization of CeO2–TiO2 mixed oxides or Ce2Ti2O7 pyrochlore phase. The CeIII oxidation process affects the colouration, leading to ecological pigments with promising applications in catalysis.

    6. Facile Gram-Scale Growth of Single-Crystalline Nanotetrapod-Assembled ZnO Through a Rapid Process (pages 3172–3176)

      Jianye Li, Hongying Peng, Jie Liu and Henry O. Everitt

      Article first published online: 3 JUN 2008 | DOI: 10.1002/ejic.200701306

      Thumbnail image of graphical abstract

      From a facile catalyst-free method, pure single-crystalline nanotetrapod-assembled ZnO was grown on a gram-scale for the first time, with high repeatability and conversion efficiency. All four arms of thenanotetrapods are cone shaped and grow in the [001] direction. The photoluminescence properties were studied and a mechanism was suggested for the growth of the nanotetrapod-assembled ZnO.

    7. Synthesis and Characterisation of Some New Zinc Carbamate Complexes Formed by CO2 Fixation and Their Use as Precursors for ZnO Particles under Mild Conditions (pages 3177–3185)

      Article first published online: 3 JUN 2008 | DOI: 10.1002/ejic.200701308

      Alkylzinc carbamates suitable as precursors to ZnO nanosized particles under mild conditions are formed by CO2 insertion into the Zn–N bonds of alkylzinc amides.

    8. Structural Chemistry of Borazines (pages 3186–3199)

      Benadir Anand, Heinrich Nöth, Holger Schwenk-Kircher and Alexander Troll

      Article first published online: 3 JUN 2008 | DOI: 10.1002/ejic.200800169

      The BN bond lengths and the planar borazine ring are distorted in the solid state by substituents in three different ways: a) by retaining the planarity of the borazine ring but with substituents bent up and down thering, b) by substituents that induce different BN bond lengths and bond ring bond angles and c) by distortion of the borazine ring into a chair shaped or twisted ring.

    9. β-Diketonate, β-Ketoiminate, and β-Diiminate Complexes of Difluoroboron (pages 3200–3211)

      Felipe P. Macedo, Chengeto Gwengo, Sergey V. Lindeman, Mark D. Smith and James R. Gardinier

      Article first published online: 3 JUN 2008 | DOI: 10.1002/ejic.200800243

      Thumbnail image of graphical abstract

      A series of β-diketonate, β-ketoiminate, and β-diiminate complexes of difluoroboron have been prepared to evaluate the effects of chelate ring substitution on the structural and electronic properties. The electron-accepting nature of the ligands likely facilitates unusual coordination chemistry.

    10. Ruthenium Complexes Bearing Bulky Pentasubstituted Cyclopentadienyl Ligands and Evaluation of [Ru(η5-C5Me4R)(MeCN)3][PF6] Precatalysts in Nucleophilic Allylic Substitution Reactions (pages 3212–3217)

      [Ru(η5-C5Me4R)(MeCN)3][PF6] (R =tBuCH2, iPr, tBu and CF3) complexes were synthesized and evaluated as catalysts for nucleophilic allylic substitution reactions.

    11. Solvent Effects on Catalytic Epoxidation of Alkenes by Tetra-n-butylammonium Periodate and (Tetraarylporphyrinato)manganese(III) (pages 3218–3224)

      Daryoush Mohajer and Massoumeh Abbasi

      Article first published online: 3 JUN 2008 | DOI: 10.1002/ejic.200800253

      In the epoxidation of cyclooctene and cis-stilbene by tetra-n-butylammonium periodate and (tetraarylporphyrinato)manganese(III) in the presence of imidazole in CH2Cl2, the molecular size and acidity of the alcohols played important roles in determining the epoxidation yields and the cis- to trans-stilbene oxide ratio and in the generation and stabilization of the [Mn(por)(O)(im)]+ species.
