Mossbauer study of the three-coordinate planar Fe (super)II thiolate complex [Fe(SR) (sub)3] (super)- (R= C (sub)6 H (sub)2 -2,4,6-tBu (sub)3): model for the trigonal iron sites of the MoFe (sub)7 S (sub)9 :homocitrate cofactor of nitrogenase

Research has been conducted on the iron sulfur clusters. The results of the Mossbauer investigation of the high-spin ferrous complexes with the extracted zero-field splittings, electric field gradient tensors, A-tensors and isomer shifts are presented.
