On the basis of synthesis of bis-(benzohydroxamato) oxoisopropoxovanadium(IV) compound containing bezohydroxamatic acid, the titled complex has been synthesized and characterized by elemental analyses and IR, ~1H NMR, ~(13)C NMR, ~(15)V NMR and UV-vis spectroscopies. The X-ray structure of titled complex has been determined to be in triclinic, P1-bar with a = 1.1119(3) nm, b = 1. 1735(3) nm, c = 0.8660(2) nm, α = 96.84(1)°, β = 106.93)(1)°, γ = 88.97(1)°, V = 1.0731(2) nm~3, D_c = 1.415 g/cm~3, Z = 2, F(000) = 478, μ = 5.06 cm~(-1). The investigation of the titled complex as structural unit has been performed by ab initio (GTO-6-31d) calculation and the stability of the complex, molecular orbitals, the population regularities of the atomic net charges have been discussed.
