  Synthesis and crystal structures of dinuclear oxotungsten(VI) diolato complexes

  摘要：

  Dinuclear complexes [W2O3L2(HL)2] [H2L = 2,3-dimethylbutane-2,3-diol (H2pin), trans-cycloheptane-1,2-diol (H2chpd) or trans-cyclooctane-1,2-diol (H2Cocd)] were prepared in high yield by hydrolysis of [W(eg)(pin)2] (H2eg = ethane-1,2-diolate), [W(chpd)3] and [W(cocd)3] in alcoholic solution. X-Ray diffraction studies showed that each tungsten(VI) ion is bonded to one diolate, one hydrogendiolate, one terminal and one bridging oxide ligand. Two tungsten-centred units are also linked together by intramolecular O...-O hydrogen bonds between the diolate and hydrogendiolate ligands. The geometry of the dinuclear unit is dependent on the nature of the diolate ligands.

  corresponding binaphthyl acetates react with trisdiolatetungsten(VI) complexes [W(eg)3] and [W(eg)(pin)2] (eg=ethanediolate dianion, pin=pinacolate dianion) forming heteroleptic complexes [W(X2bino)(diolato)2]. The X-ray crystal structure determinations confirmed that the isolated compounds are made of monomeric tris(diolate)tungsten(VI) molecules in which the central tungsten atom is bonded to six oxygen

• Stereochemistry of six-coordinated tungsten(VI) complexes having one rigid chiral bidentate ligand and two flexible bidentate ligands: Stereo-selective formation of Δ- and Λ-forms induced by the chiral ligand

  complexes with one rigid chiral bidentate ligand, 1,1′-bi-2-naphthol (bino) 1, and two flexible bidentate ligands (f-bls), pinacol (pin) or ethylene glycol (en), were prepared, and their stereochemistry was discussed. Generally, metal complexes with three f-bls produce enantiomeric Δ- and Λ-forms. Other types of isomerism are produced by f-bls, which are attributable to their conformation, i.e., δ- and λ-forms

  六配位钨 (VI) 配合物与一个刚性手性双齿配体 1,1'-bi-2-萘酚 (bino) 1和两个柔性双齿配体 (f-bls)、频哪醇 (pin) 或乙二醇 (en )，并讨论了它们的立体化学。通常，具有三个 f-bl 的金属络合物会产生对映异构体 Δ- 和 Λ- 形式。其他类型的异构现象由 f-bls 产生，这归因于它们的构象，即δ-和 λ-形式。虽然Δ-和Λ-对映异构体的构象异构产生非对映异构体，但非对映异构体之间的能量差异很小，小于几kcal mol -1. 因此，f-bls 的构象异构在配位化学中并不显着。我们发现一种刚性手性双齿配体的引入控制了复合物的 Δ- 和 Λ- 立体化学。( R )-bino的构象产生 Δ-异构体，( S )-bino 的构象提供 Λ-异构体。我们还进行了理论研究来支持我们的观察。

  The title compound, [W(C3H5ClO2)(C6H12O2)(2)], is a mononuclear complex in which the central tungsten(VI) cation is surrounded by six oxygen donors of three chelating diolato ligands. The WO6 unit adopts a distorted octahedral geometry.
• Preparation and structural studies of tungsten(VI)diolato adducts of phenol and aniline
  作者：Ari Lehtonen、Reijo Sillanpää

  日期：1995.7

  The tungsten(VI)diolato complex, [W(eg)(pin)(2)] (H(2)eg = 1,2-ethanediol, H(2)pin = 2,3-dimethyl-2,3-butanediol) forms adducts with phenol and aniline. X-ray structural studies and spectral measurements (UV and IR) show that the formation of those adducts is due to hydrogen bonding between OH or NH2 groups of adductant and diolato oxygen atoms. The effect of hydrogen bonding on the octahedral WO6 centre is minimal, but the conformation angles of the five-membered chelate ring change considerably. Hydrogen bonding does not promote alcoholato exchange reactions.
