Cobalt(II) and nickel(II) complexes of N(4 ') substituted 3-and 4-acetylpyridine thiosemicarbazones

Co-II and Ni-II complexes of N(4')-methyl and N(4')-ethyl thiosemicarbazones derived from 3- and 4-acetylpyridine have been prepared and characterized by microanalyses, magnetic susceptibility and molar conductivity measurements and by their electronic, i.r. and n.m.r. (in the case of Ni-II complexes) spectra.
