  摘要：

  The reaction of o-C6H4(AsMe2)(2) with VCl4 in anhydrous CCl4 produces orange eight-coordinate [VCl4{o-C6H4(AsMe2)(2)}(2)], whilst in CH2Cl2 the product is the brown, six-coordinate [VCl4{o-C6H4(AsMe2)(2)}]. In dilute CH2Cl2 solution slow decomposition occurs to form the V-III complex [V2Cl6{o-C6H4(AsMe2)(2)}(2)]. Six-coordination is also found in [VCl4{MeC(CH2AsMe2)(3)}] and [VCl4{Et3As)(2)]. Hydrolysis of these complexes occurs readily to form vanadyl (VO2+) species, pure samples of which are obtained by reaction of [VOCl2(thf)(2)(H2O)] with the arsines to form green [VOCl2{o-C6H4(AsMe2)(2)}], [VOCl2{MeC(CH2AsMe2)(3)}(H2O)] and [VOCl2(Et3As)(2)] Green [VOCl2(o-C6H4(PMe2)(2)}] is formed from [VOCl2(thf)(2)(H2O)] and the ligand. The [VOCl2(o-C6H4(PMe2)(2)}] decomposes in thf solution open to air to form the diphosphine dioxide complex [VO{o-C6H4(P(O)Me-2)(2)}(2)(H2O)]Cl-2, but in contrast, the products formed from similar treatment of [VCl4(o-C6H4(AsMe2)(2)}] or [VOCl2(o-C6H4(AsMe2)(2)}] contain the novel arsenic(V) cation [o-C6H4(AsMe2Cl)(mu-O)(AsMe2)](+). X-ray crystal structures are reported for [V2Cl6(o-C6H4(AsMe2)(2))(2)]. [VO(H2O)(o-C6H4(P(O)Me-2)(2))(2)]Cl-2, [o-C6H4(AsMe2Cl)(mu-O)(AsMe2)]Cl center dot[VO(H2O)(3)Cl-2] and powder neutron diffraction data for [VCl4{o-C6H4(AsMe2)(2))(2)]. (C) 2010 Elsevier Ltd.
