Metal Complexes of Pyridine-3-Carboxyaldehyde Thiosemicarbazone

摘要

Complexes of copper(II), cobalt(II), nickel(II), manganese(II), iron(II) and iron(III), zinc(II) and silver(I) with pyidine-3-carboxaldehyde thiosemicarbazone (HNAT) are reported. Analytical, spectral, magnetic and conductance studies indicate that HNAT acts as a bidentate ligand in all its complexes coordinating through the nitrogen of the pyridine ring and sulphur atom. Polymeric six-coor-dinated ligand bridged structures have been proposed for all the complexes except [Co(HNAT)Cl_2], which has a polymeric four-coordinated structure.
