Abstract

Abstract: The synthesis of the sulfur-bridged iron (I1) complexes (FeL) 2 and (FeL') 2 is described. Differences in the steric constraints of the tetradentate N2Sz donor ligands N, N'- dimethyl-N, N '-bis (2-mercaptoethyl) ethylenediamine (LH2) and N, N '-dimethyl-N, N'-bis (2- mercaptoethyl)-1, 3-propanediamine (L'H2) are reflected in the physical properties of the complexes. Magnetic and Mossbauer studies over a temperature range show both (FeL) 2 ...
