Template Synthesis and Characterization of Some Bivalent 3d Metal Complexes of Acetylacetonebis(2-Thenoylhydrazone)

摘要

2Complexes of the types M(H2acacth)cl2M = Mn(II), Co(II), Ni(II) and Cu(II) and M(acacth)(H2O)2M = Ni(II), Cu(II) and Zn(II); H2acacth = acetylacetonebis(2-thenoylhydrazone) have been isolated through template reaction of the metal chloride, acetylacetone (acac) and 2-thenoylhydrazine (th) in neutral and alkaline solutions, respectively. The complexes have been characterized by physico-chemical methods, such as molar conductance, magnetic susceptibility, spectroscopy (IR, NMR, electronic, photoacoustic and ESR) and X-ray powder diffraction.
