英文摘要The reaction of [VO(R-1-acac)(2)](R-1 = Me or Et; acac = acetylacetonate) with Na[HB(pz)(3)] (pz = pyrazole) or Na[HB(3,5-Me(2)pz)(3)] in MeOH gave a series of new oxovanadium (IV) complexes: [VO{HB(pz)(3))(Me-acac)] (1), [VO{HB(3,5-Me(2)pz)(3)}(Me-acac)] (2), [VO{HB(pz)(3))(Et-acac)] (3) and [VO{HB(3,5-Me(2)pz)(3)}(Et-acac)] (4), respectively. All complexes have similar distorted octahedral coordination about vanadium, [VO(N3O2)], in which the basal plane is defined by the N-4, N-6 atoms from the tridentate ligand and the O-2, O-3 atoms from the R-1-acac ligand. However, the dihedral angles between the plane formed by O-2, V and O-3, and the plane of the pentane-2, 4-dionato ligand (O2, C1, C2, C3 and O3) are variously different; 3.59 degrees for 1, 74.54 degrees for 2, 0.92 degrees for 3, and 29.50 degrees for 4, respectively. In addition, ab initio calculations on 1, 2, 3 and 4 have given the energies and characters of the selected MOs, the atomic net charge and the NBO bond order. The order of stability of the complexes is 1 congruent to 2 congruent to 4 > 3.
