| 摘 要： | The title compound has been prepared by reaction of VOSO_4 with hydroxyacetic acid in aqueous solution, adding KOH to a suitable pH value. The crystals are monoclinic, space group P2_1/b with cell parameters: α=10.075(2), b=9.857(3), c=14.314(3), γ=115.29(2)°, Z=4. Intensities of 1714 independent reflexions having I≥3σ(I) were collected on a CAD4 diffractometer with MoKα radiation. The structure was solved by Patterson and direct methods and refined by full matrix least-squares method to R=0.060. In the complex the ratio of centric V atom to hydroxyacetate ligands is M:L=1:3, two hydroxyacetate ligands are chelated to V atom in a cis arrangement, the other is monodentate ligand with a carboxyl O atom to grasp the cation VO~(2+).
