Nickel(II) complexes with five 4-acetamidobenzaldehyde N(4)-substituted thi
osemicarbazones have been prepared in EtOH solution and characterized by ph
ysical and spectral methods. N.m.r., i.r. and electronic spectra of the thi
osemicarbazones and their complexes, along with physical properties of the
complexes, have been recorded. These thiosemicarbazones coordinate as anion
ic ligands lin the thiosemicarbazone moiety's azomethine nitrogen and thiol
ate sulfur [upon loss of the N(2) hydrogen] when reacted with NiCl2 in the
presence of Et3N or with Ni(OAc)(2).
