Iron(II) and iron(III) complexes of 2,4-dithiobiuret

Abstract

SummaryFerrous and ferric complexes of 2,4-dithiobiuret (Dtb) of the type Fe(Dtb)mX n where m, n = 1-3, and X = CI-, Br-, I-and SO42-, and a neutral Fe(Dtb-H)~ complex have been synthesized and characterised by elemental analyses, magnetic susceptibility, i.r., electronic and M6ssbauer spectroscopic studies. From its i.r. spectrum Dtb was found to act as a S,S-coordinating bidentate chelate. The magnetic moment, electronic and M6ssbauer spectra are consistent with a low spin distorted octahedral structure for the ferric complexes and a high spin form for ferrous complexes.
