Two ligands were derived from two sciff-bases of salicylaldehyde with 1,2-diaminopropane, Sal-DAP (L1) and salicylsaldehyde with 2-picolyamine, Sal-PA (L2) and their novel dioxovanadium complexes were synthesized. The complexes C1, [VO2(Sal-DAP)] and C2, [VO2(Sal-PA)] are characterized by conductivity measurements, magnetic susceptibility, UV-Vis, IR, thermal analysis, 1H- and 13C-NMR.The molecular structure of the complexes C1 and C2 were confirmed using the DFT calculation to obtain the optimized geometries using the Gaussian09 program at the B3LYP/LANL2DZ level of theory. The vanadium atoms in the two complexes were coordinated in distorted trigonal bipyramidal geometries with L1 acting as a tridentate ligand through nitrogen atoms and one deprotonated phenol oxygen atom leaving the other phenol group free, and L2 acting as a tridentate ligand through nitrogen atoms and deprotonated phenol oxygen atom.
