AbstractA series of oxovanadium(IV) complexes: TpVO(pzH)(2,4-Cl-C6H3-OCH2COO) (1), TpVO(pzH)(C6H5-OCH2COO) (2), TpVO(pzH)(P-Cl-Cr6H4-COO) (3), TpVO(pzH)(3,5-NO2-C6H3-COO) (4), Tp*VO(pzH*)(p-Cl-C6H4COO) (5) and Tp*VO(pzH*)(P-Cl-C6H4-COO) center dot CH3OH (6) (Tp = hydrotris(pyrazolyl)borate, pzH = pyrazole, Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, pzH* = 3,5-dimethylpyrazole) were synthesized and their crystal structures were determined by X-ray diffraction. In all the complexes, the vanadium ions are in a distorted-octahedral environment with a N4O2 donor set. Hydrogen bonding interaction exists in each complex. Complexes 1 and 2 are hydrogen-bonded dimers. Dimeric units of 2 are connected to one another via weak inter-molecular C-H... 0 interactions to form a 2D network on the bc-face. In 3-6 there exist intramolecular N-H center dot center dot center dot O hydrogen bonds between the neutral pyrazole/3,5-dimethylpyrazole and the uncoordinated carboxyl oxygen atom. In addition, the catalytic activity of complex 2 in a bromination reaction in phosphate buffer with phenol red as a trap was evaluated by UV-Vis spectroscopy. Furthermore, the elemental analyses, IR spectra and thermal stabilities were recorded. (C) 2009 Elsevier Ltd. All rights reserved.
