performed. Structural analyses reveal that the vanadium atom has a distorted trigonal bipyramidal geometry with a N3O2 donor set in 1; distorted octahedral geometry in 2, 4 and 5 with donor sets of N5O, N3O3 and N3O3, respectively; a distorted pentagonal bipyramidal geometry with a N3O4 donor set in 3. In addition, the five new complexes with abundant intro- and inter-hydrogen bonding interactions exhibited
