    1. Titanium Complexes

      Structural Consequences in α- and β-Glucopyranosidato Complexes of Cp*TiCl3 (pages 5295–5298)

      Dirk Schwidom, Daniela Zeysing, Michael Schmidt and Jürgen Heck

      Article first published online: 3 NOV 2009 | DOI: 10.1002/ejic.200900753

      The change of the configuration at only one carbon atom of the monosaccharide ligand induces a change of the absolute configuration of the metal centre of the corresponding titanium complexes. The configurational change is easily seen by a projection of the molecular structure along the molecular C2 axis: The “S” shape of 1 changes into an overall inverse “S” shape of 2.

    2. Sol–Gel Synthesis

      Aluminum Alkoxide Fluorides Involved in the Sol–Gel Synthesis of Nanoscopic AlF3 (pages 5299–5301)

      Anton Dimitrov, Julia Koch, Sergey I. Troyanov and Erhard Kemnitz

      Three aluminum alkoxide fluorides as intermediates of the fluorolysis of aluminum isopropoxide with HF in pyridine have been isolated and structurally characterized [see structure of Al7F104-O)(O-Pr)9(Py)3; yellow Al, green F, red O, blue N, gray C]. These compounds represent possible snapshots in the consecutive fluorolytic sol–gel formation of nanoscopic AlF3.

    1. Three Is the Magic Number

      Formation of Unusual Trinuclear Assemblies: Scope and Mechanism of Zn(salphen)-Templated Activation of Pyridine-Alcohol Substrates (pages 5307–5318)

      Marta Martínez Belmonte, Eduardo C. Escudero-Adán, Jordi Benet-Buchholz and Arjan W. Kleij

      Article first published online: 14 OCT 2009 | DOI: 10.1002/ejic.200900862

      Thumbnail image of graphical abstract

      The Zn(salphen)-templated synthesis and solution and solid-phase analysis of a series of unusual trinuclear supramolecular assemblies is reported. Under suitable conditions, a non-symmetrical Zn complex comprising two monoanionic pyridine-alcohol ligands is formed, which combines with two Zn(salphen) units to provide the Zn3 structures (see figure). The scope and mechanism of formation related to this templated process have been investigated.

    2. Iron Coordination Chemistry

      Article first published online: 28 OCT 2009 | DOI: 10.1002/ejic.200900794

      Thumbnail image of graphical abstract

      Unsupported hydroxo- and oxo-bridged diiron(III) complexes, and monomeric iron(III) complexes were synthesized with with pyridylbis(aminophenol) ligands. The oxo-bridged diiron(III) complex could be protonated to generate its hydroxo-bridged analog, but the hydroxo-bridged dimer could not be deprotonated to generate its oxo-bridged dimer.

      Thumbnail image of graphical abstract

      Acidity brings stability: Thermal stability of over 400 °C is achieved for metal-organic frameworks, if copper(II) is linked by 1,4-benzenedisulfonate or 1,3,5-benzenetrisulfonate. The respective sulfonic acids with appropriate substitution pattern are prepared in an efficient and scalable two-step protocol from bromobenzene derivatives.

    4. Hybrid Inorganic–Organic Networks

      Thumbnail image of graphical abstract

      Isomorphous Ni and Zn complexes of the dibenzoyl derivative of clodronic acid, 1 and 2, and the isostructural corresponding complexes of clodronic acid, 3 and 4, were prepared and characterized.

      Thumbnail image of graphical abstract

      The synthesis of the N,N-diallylcarbamato complex Cu(O2CNAllyl2)2 led to the formation of a polymeric CuI complex [CuI4Cl4(NHAllyl2)4]n. Surprisingly, the reduction of CuII to CuI is coupled to the oxidation of diallylamine to 3,4-dimethylpyrrole.

      MnI- and ReI(CO)3 complexes of imidazolyl-based phosphane ligands were prepared. The Mn(CO)3 complexes were studied as CO-releasing molecules (CORMs). Within the series of compounds prepared, the substitution pattern of the imidazolyl groups was found to significantly influence the CO release efficiency and stoichiometry.

      Thumbnail image of graphical abstract

      Gold(I) complexes with isocyanocarbazole ligands were prepared. The gold complexes display a redshift in the emissions relative to that of the free ligand. The presence of electron-withdrawing substituents in 3,6-dibromo-9-(4-isocyanophenyl)carbazolequenches the luminescence, but with the introduction of a gold atom some luminescence is recovered.

      The isomerizations of (RC≡CR)3W(CO)n (n = 3, 2) to (η6-C6R6)W(CO)n are predicted by density functional theory to be very exothermic. However, the isomerizations of (RC≡CR)3W(CO) and (RC≡CR)3W to (η6-C6R6)W(CO) and (η6-C6R6)W, respectively, are predicted to be nearly thermoneutral (R = CH3) to highly endothermic (R = CF3).
