A new series of (diphosphine)Ni-bridged double-butterfly Fe/S clusters [(μ-RS)( μ-S]CS)Fe2(CO)6]2[Ni(- diphosphine)] (1-6, R = p-MeC6H4, Ph, n-Bu; diphosphine = dppe, dppv, dppb, dppf) was prepared by a new type of sequential reactions of the m-CO-containing anions [(μ-RS)( μ-CO)Fe2(CO) 6]- (type A anions, generated in situ from Fe 3(CO)12, RSH, and Et3N) with excess CS 2, followed by treatment of the resulting m-CS2-containing anions [(μ-RS)( μ-S]CS)Fe2(CO)6]- (type B anions) with various (diphosphine)NiCl2 complexes. In addition, two of the type A anions, namely [(μ-p-MeC6H4S)( μ-CO)Fe2(CO)6]- (A1) and [(μ- PhS)( μ-CO)Fe2(CO)6]- (A2) were successfully isolated as their [Et3NH] and [Ph4P] salts, respectively. Products 1-6 as well as the two isolated complex salts A1[Et 3NH] and A1[Ph4P] were fully characterized by elemental analysis and spectroscopy, and particularly for 4, 6, A 1[Et3NH], and A2[Ph4P] by X-ray crystallography.
