Results of Ab Initio calculations are reported for the heterobinuclear complex of Cu(Ⅱ) VO(Ⅱ) at ROHF/LANL2MB level,the equilibrium geometries in singlet and triplet configuration of Cu(Ⅱ) VO(Ⅱ) have been optimized and the harmonic vibrational frequencies have been calculated.Results show that the triplet electronic configuration of the complex is more stable than the singlet one.The spin populations of electrons are predominantly located on the O(5),V(6) atom,and only a little population is found on ...
