Abstract
The title complex, [VO2{C6H5C(O)CHC(CH3)NNC(O)CH2(NC5H5)}] · C2H5OH, was synthesized and characterized by elemental analysis and spectroscopy. Yellow crystals of the complex are monoclinic, space group P21/a with a = 10.690(2), b = 16.008(3), c = 13.164(4)Å, β = 107.03(2)°, V = 2153.9(18)Å3, F(000) = 880 and Dc = 1.305 g cm−3 for Z = 4. X-ray structure analysis shows that the vanadium coordination number is five and the coordination polyhedron is a distorted trigonal bipyramid.
