Synthesis, characterization and crystal structure of oxovanadium(IV) complex with tridentate o-van-gly and bidentate phenanthroline.

Abstract A novel oxovanadium(IV) complex with tridentate schiff base and bidentate phenanthroline ligands, VO(o-van)(phen) ·2H2O[o-van-gly: o-vanillin-glycine; phen: phenanthroline], was synthesized and characterized by elemental analysis, IR and UV-vis spectra. The crystal structure was determined by X-ray single crystal diffraction analysis. The crystal of title complex (C22H21N3O7V, Mw = 490.36) belongs to triclinic, space group P-1 with the following crystallographic parameters: a = 9.247(3) Å, b = 10.125(4) Å, c = 13.100(5) Å, a = 106.343(6)°, ß = 96.042(7)°, ? = 101.726(7)°, V = 1135.0(7) Å3, Z = 2, Dc = 1.435 Mg · m-3, µ(MoK a = 0.485 mm-1, F(000) = 506, and final R1 = 0.0779, wR2 = 0.1598 for observed reflections 1606 (I > 2s(I)). V(IV) is six-coordinate with three oxygen atoms and three nitrogen atoms in a distorted octahedral geometry. The complex forms a 3-D network via p–p stacking and hydrogen bonds. [ABSTRACT FROM AUTHOR]
