Abstract
A novel oxovanadium complex was obtained by the reaction of VOSO4 · 3H2O with tripyrazolylborate sodium in MeOH. The complex (1) was characterized by element analysis, IR spectroscopy, 1HNMR and its crystal for X-ray diffraction recrystallized from saturated CH3CN solution. The compound crystallizes in the monoclinic, space group Pbca, with cell dimensions of a = 15.531(2) Å; b = 18.007(2) Å; c = 10.725(2) Å; V = 2,999.4(8) Å3 and D calc = 1.533 g/cm3 for Z = 4. The structure was solved by direct methods and refined to an R-value of 0.0401. Structure analysis show that it is a di-μ-oxo-bistripyrazolylborato dioxo vanadium (V) complex with lattice of diacetonitrile. In addition, the electronic structure and the bonding characters of the complex were analyzed with ab initio calculations.
