Abstract
Reduction of 2-cyanopyridine by sodium in dry methanol in the presence of N (4)-methylthiosemicarbazide produces 2-pyridineformamide N(4)-methylthiosem icarbazone, HAm4M. Complexes with iron(III), cobalt(II,III) and nickel(II) have been prepared and characterized by molar conductivities, magnetic susc eptibilities and spectroscopic techniques. In addition, the crystal structu res of HAm4M, [Ni(Am4M)(OAc)], [Fe(Am4M)(2)]ClO4 and [Co(Am4M)(2)]ClO4 have been solved. Coordination is via the pyridyl nitrogen, imine nitrogen and thione or thiolato sulfur when coordinating as the neutral and anionic liga nd, respectively.
