H2O(21)The complexes were characterized by elementel analysis, mass spectrometry, 1H-NMR, 13C-NMR, thermic analysis, powder X-Ray difraction, IR and UV-vis techniques. Crystal and molecular structures of ten complexes were determined by X-ray analysis. Concequently, it has been determined that complexes 8, 15, 16 ve 20 have square-pyramidal, 4 ve 19 square-planar, 9 have trigonal bipyramidal, and the others complexes have octahedral geometries.Key Words: Mn(II), Cd(II), Co(II), Ni(II), Cu(II), Zn(II) and Pb(II) complexes, p-methylbenzoic acid, nicotinamide, isonicotinamide, diethylnicotinamide, crystal structure.
