Magnetic and spectral studies of transition metal complexes of salicylaldehyde-2-aminoacetophenone-2-thenoylhydrazone

Abstract: Salicylaldehyde-2-aminoacetophenone-2-thenoylhydrazone (H2saath) has been found to react with the transition metal salts to form the complexes VO(H2saath)2SO4, M(H2saath)2Cl2 and M(H saath)2 [M=OV(IV), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)]. The complexes have been characterized by elemental analyses, molar conductance, magnetic susceptibility, electronic and photoacoustic, ESR, IR,1H and13C NMR studies. X-ray diffraction study suggests a tetragonal unit lattice for zinc(II) and an orthorhombic one for copper(II) complexes.
