Abstract
A di(μ-oxo)-bridged dinuclear complex, [VO2(pamh)]2 was isolated by reacting bis(acetylacetonato)vanadium(IV) and the Schiff base, N-(anisoyl)-N′-(picolinylidene)-hydrazine (Hpamh) in acetonitrile. The complex crystallizes in the space group \(P\bar 1 \) ;1; (#2) on crystallographic inversion center. Crystal data: a = 8.2202(12) Å, b = 9.8389(19) Å, c = 10.1907(17) Å, α = 68.245(15)°, β = 74.47(2)°, γ = 66.710(19)°, V = 696.0(2) Å3, and Z = 1. The physical properties of the complex and the structural parameters are consistent with the +5 oxidation state of the metal ions. The monomeric VO2(pamh) unit is square-pyramidal. The planar mononegative ligand (pamh−) coordinates the metal ion via the pyridine-N, the imine-N, and the amide-O atoms. One of the oxo groups completes the NNOO basal plane and also participates in the Vndash;Ondash ;V bridge formation. The other oxo group satisfies the fifth apical coordination site. The molecular structure of the dimeric complex, [VO2(pamh)]2 can be described as two edge-shared distorted VO4N2 octahedra.
