A new cis-dioxovanadium (V) complex [VO2(C9H8N3O3)](C5H5N) involving a carboxyl group coordination employing a tridentate Schiff Base derived from pyruvic acid and isonicotinyl hydrazide is reported. This complex crystallizes in triclinic, space group P(1-) with a = 7.3522 (12), b = 7.8376(13), c = 14.898(2)(A), α= 84.010(2),β= 86.568(2), γ = 64.586(2)°, V = 771.1(2)(A)3, Z = 2, F(000) = 376, Mr = 368.22, Dc = 1.586 g/cm3, μ = 0.677 mm-1, R = 0.0421 and wR = 0.1253. The vanadium atom of the dioxovanadium (V) is five-coordinated to furnish a distorted trigonal bipyramid geometry.
