2-Aminoacetophenone-2-thenoylhydrazone complexes of bivalent 3d metal ions

Abstract

2-Aminoacetophenone-2-thenoylhydrazone, Haath, C4H3SC(O)NHN=C(Me)C6H4NH2-o, forms complexes with metal(II) salts of empirical compositions [VO(Haath)2SO4], [M(Haath)2Cl2] [M=CoII, NiII, CuII or ZnII] and [M(aath)2] [M=VIVO, CoII, NiII, CuII or ZnII] which have been characterized by elemental analyses, molar conductance, magnetic susceptibility, electronic, e.s.r., i.r. and n.m.r. (1H and13C) spectral studies. X-ray and electron diffraction patterns have been obtained in order to elucidate the structure of the CuII complexes. Photoacoustic spectra of powder NiII complexes have been recorded and interpreted in the light of u.v./vis. spectra. © 1989 Chapman and Hall Ltd.
