摘要：
Two new oxovanadium (IV) complexes VO(HB(pZ)(3),B(PZ)2) (1) and VO(B(PZ)4)2 (2) have been obtained by the reaction of oxovanadium sulfate with the corresponding ligands KHB(PZ)3, KH,B-2(pz)2 and KB(PZ)4, respectively. The two complexes were characterized by elemental analyses, IR, UV-Vis and X-ray diffraction. Complex I crystallizes in the orthorhombic space group, Pca2(1). Complex 2 crystallizes in the orthorhombic space group, Pna2(1). In both complexes, five nitrogen atoms and one oxygen atom coordinate to the vanadium atom, forming a distorted octahedral geometry (VON5). In addition, related spectra characterization, hydrogen-binding properties, structural configuration and quantum chemistry calculations are also discussed. (c) 2007 Elsevier Ltd. All rights reserved.
