The addition of [n-Bu2SnCl2] to a solution of [S4N3][Cl] in liquid ammonia gave after extraction of the dry reaction mixture the new tin disulfur dinitrido compound [{n-Bu2Sn(S2N2)}2] (1). Reaction of [{n-Bu2Sn(S2N2)}2] (1) with the pentamethylcyclopentadienyl (Cp*) iridium derivatives [{IrCl(μ-Cl)(η5-C5Me5)}2] or [μ5-C5Me5)IrCl2(PPh 3)] gave different products, which were dependent on the reactant ratios. A 1:1 reaction between 1 and [{IrCl(μ-Cl)(η5-C5Me5}2] gave only [η5-C5Me5)Ir(S2N 2)] (2) in moderate yield; the same product in higher yield was obtained from a 2:1 reaction between 1 and [(η5-C5Me5IrCl2(PPh 3]. Reaction of 1 and [ζ5-C5Me5)2IrCl2 (PPh3)] (1:1 molar ratio) in the presence of NH4[PF6] gave the unusual bimetallic species [η5-C5Me5IrCl(PPh3)S 2N2)Ir(η5-C5Me5] [PF6] (3). The) X-ray crystal structures of 1, 2, and 3 are reported.
