MOSSBAUER SPECTRA OF SOME TRIS(N,N-DISUBSTITUTED DITHIOCARBAMATO)IRON(3) COMPOUNDS

Mossbauer spectra have been measured at room temperature and at liquid nitrogen temperature for 24 tris(N,N-disubstituted dithiocarbamato)iron(III) complexes, 10 of which were unreported hitherto. There are no systematic variations in isomer shift but the quadrupole splittings are quite sensitive to the nature of the nitrogen substituents and to temperature. Ligands with straight-chain alkyl substituents on nitrogen and those ligands derived from cyclic secondary amines give small room-temperature splittings and have been interpreted as favoring covalent iron-sulfur bonding. © 1969, American Chemical Society.
