摘要: The crystal structure of the monomeric vanadium(III) species mer-[V(bipy)Cl(3)(MeCN)] (1; bipy = 2,2'-bipyridine) is reported. solvothermal reaction [V(bipy)Cl(3)(MeCN)]with Na(O(2)CPh) yields T-shaped cluster [V(3)(O)Cl(3)(O(2)CPh)(2)(bipy)(2)(OEt)(2)], magnetic studies which show strong intramolecular antiferromagnetic coupling giving a well isolated S 1 ground state. Solvothermal treatment with triols series polymetallic clusters [V(4)Cl(6)(thme)(2)(bipy)(3)], [V(3)Cl(4)(Hcht)(2)(bipy)(2)]Cl and [V(8)(OH)(2)Cl(4)(cht)(4)(O(2)CPh)(6)(bipy)(2)], structurally related to previously reported {M(4)} centred triangles. Magnetic this reveal very weak exchange local zero-field splitting effects.
