Abstract

Bimetallic complexes [(η5-C5R5)M(S2N2)Au(PPh3)][ClO4] and tetrametallic species [{(η5-C5R5)M(S2N2)Au}22-P^P)][ClO4]2 (R = H, M = Co; R = Me, M = Ir; P^P = dppm or dppe) can be prepared by treatment of [(η5-C5R5)M(S2N2)] with gold(I) electrophiles generated by chloride abstraction from [AuCl(PPh3)] or [(AuCl)22-P^P)]. X-Ray crystallography of [(η5-C5Me5)Ir(S2N2)Au(PPh3)][ClO4] and [{(η5-C5Me5)Ir(S2N2)Au}22-dppm)][ClO4]2 confirms auration of the metal-bound nitrogen atom of the MS2N2 ring. π-Stacking of theMS2N2 rings occurs within both structures.
