      Mortreux-type catalysts promote cross metathesis of (prop-1-yn-1-yl)ferrocene (1) with functionalized alkynes 2 to give the corresponding alkynylferrocenes 3 with good selectivity and yields. The structures of selected products were determined by X-ray crystallography, and the results were correlated with DFT calculations. A series of alkynes 4-XC6H4C≡CFc (Fc = ferrocenyl) was studied by electrochemicalmethods.

      The products in the solid state obtained from the reactions between 2,4,6-tris(2-pyridyl)-1,3,5-triazine and I2, Br2, IBr, and ICl have been isolated and characterized. All compounds are salts containing the protonated donor counterbalanced by polyhalide anions of various complexity. In particular, (H3tptz3+)(I3Br4)(IBr2)2 provides the first example of a planar I3Br4 moiety.

      Jeffrey A. Rood, Sondra E. Hinman, Bruce C. Noll and Kenneth W. Henderson

      Article first published online: 25 JUL 2008 | DOI: 10.1002/ejic.200800540

      A set of magnesium imides derived from fluoro- and chloro-substituted anilines have been synthesized and characterized in the solid state. Either tetrameric cubane or hexameric prismatic structures are obtained depending on the relative steric hindrance within the aggregates. In addition, a novel decametallic cage complex has been characterized as a minor side product arising from C–F bond cleavage.

    5. Effective Repression of the Fragmentation of a Hexadentate Ligand Bearing an Auto-Immolable Pendant Arm by Iron Coordination (pages 3943–3947)

      Vitalie Stavila, Yvon Stortz, Cécile Franc, Delphine Pitrat, Philippe Maurin and Jens Hasserodt

      Article first published online: 25 JUL 2008 | DOI: 10.1002/ejic.200800419

      With the aim to develop a molecularimaging probe, a low-spin ferrous complex (MRI silent) was synthesized to test whether it fragments spontaneously to aparamagnetic ferrous complex (MRI active)upon enzymatic removal of a glycosylmoiety. While the underlying hexadentate ligand indeed rapidly disintegrates to a pentadentate one under physiological conditions, the metal complex does not.

    6. Lanthanide Complexes of 2,2′,2″-(10-{[Hydroxy(phenyl)phosphoryl]methyl}-1,4,7,10-tetraazacyclododecan-1,4,7-triyl)triacetic Acid: Structural Characterisation of Intermediates from the Proposed Complexation Mechanism in the Systems of LnIII-dota-Type Ligands (pages 3948–3956)

These O-coordinated complexes are the first structurally characterised intermediates on the path from the ligand to the classical in-cavity N,O-coordinated complexes.

    7. Heterometallic CoIII–LnIII (Ln = Gd, Tb, Dy) Complexes on a p-Sulfonatothiacalix[4]arene Platform Exhibiting Redox-Switchable Metal-to-Metal Energy Transfer (pages 3957–3963)

      The emission of the heterometallic [Co(dipy)3]3+–TbIII complex on a p-sulfonatothiacalix[4]arene platform can be switched on by the bulk electrochemical reduction of the CoIII block with further switching off by subsequent reoxidation of CoII.

    8. Crystal Structure, Electronic Structure, and Solid-State Electrochemistry of Cluster Complexes of M3Se74+ (M = Mo, W) with Noninnocent o-Phenanthroline and Se22– Ligands (pages 3964–3969)

      The crystal structure, electronic structure, and electrochemistry of [M3Se7(o-phen)3]X4 (M = Mo, W) cluster complexes were investigated. Strong interactions between the X and Se2 ligands of the M3Se7 cluster, observed in the crystal, can be described as donor–acceptor covalent bonding and are important enough to influence the redox behavior of the cluster.

    9. Low-Coordinate Iron Complexes Based on Bis(pyrazolyl)borate and Their Reactivity (pages 3970–3976)

      Marit Wagner, Christian Limberg and Burkhard Ziemer

      Article first published online: 25 JUL 2008 | DOI: 10.1002/ejic.200800314

      Thumbnail image of graphical abstract

      Bis(pyrazolyl)borates with bulky substituents enable the synthesis of three- and four-coordinate FeII complexes. As the BpFe units can be considered as models for the (His)2Fe moieties found in nonheme iron enzymes, attempts were also made to replace the remaining halido ligands by other residues resembling amino acids or cofactors. In the course of such studies it turned out that the BpFe core is sensitive to carboxylate functions.

      Fluorocarbonylsulfur thiocyanate wasgenerated from a gas–solid reaction of FC(O)SCl on the surface of finely powdered AgSCN. The reaction products were detected and characterized by photoelectron spectroscopy and photoionization mass spectrometry. The geometrical and electronic structures of FC(O)SSCN were investigated by theoretical calculations and PES experiments.

      Density functional theory (DFT) at the hybrid B3LYP level has been applied to the germanium clusters Ge14z (z = –8, –6, –4, –2, 0, +2, +4) starting from seven different initial configurations. An Oh omnicapped cube structure is the most stable for Ge142– followed by a hexagonal antiprism structure with a relative energy of 42.7 kcal/mol. Structures derived from the omnicapped cube are also the global minima for Ge14 and Ge142+. Structures based on the D6h hexagonal wheel are also found.

      The synthesis, crystal structure and magnetochemical characterization of the new μ-oxido cluster [Fe33-O)(μ2-CH3O)22-CH3COO)2(phen)2Cl3] is reported. The core of the complex is an isosceles triangle with a rare T-shaped geometry. Magnetic studies revealed an antiferromagnetically exchanged ST = 5/2 ground-state spin with a positive D value of about 1.5 cm–1.

      Nickel(II) complexes containing hydrotris(3,5-dimethylpyrazolyl)borate and phosphate esters were prepared and fully characterized. X-ray crystallographicstudies reveal that the phosphate ester anions are hydrogen bonded to the pyrazole moieties or to the O–H groups of water molecules. Their behavior in solution was investigated by 1D and 2D 1H NMR spectroscopic techniques.

      CoFe2O4 hollow spheres with sizes ranging from 600 nm to 1 μm were prepared through hydrothermal carbonization, followed by calcination. XRD, TEM, HRTEM, SEM, N2 adsorption–desorption, XPS, IR, and TG techniques were used to characterize the product in detail, and the magnetic properties were also investigated.
