N-1,N-4-diarylidene-S-ethylthiosemicarbazone iron(III) and nickel(II) complexes

Abstract

Template reactions of salicyl-, 5-bromosalicyl- and 2-hydroxy-1-naphth-aldehyde with S-ethylthiosemicarbazones, in the presence of FeCl3 and NiCl2, yielded the corresponding N-1,N-4-di(same/different)arylidene-S-ethylthiosemicarbazone complexes, which were characterized by elemental analysis, magnetic measurements, i.r. and H-1-n.m.r. spectra.
