The compound cis‐ [Ni(C 6 F 5 ) 2 (PhCN) 2 ] has been used as the starting material for the preparation of the bimetallic complexes [(C 6 F 5 ) 2 Ni(μ‐X) 2 Ni(C 6 F 5 ) 2 ] 2– (X = SCN, OCN, N 3 ), [(C 6 F 5 ) 2 Ni(μ‐SCN) 2 Pd(C 6 F 5 ) 2 ] 2– , [(C 6 F 5 ) 2 Ni(μ‐NCS) 2 Pd‐(dppe)] [dppe = 1,2‐bis(diphenylphosphanyl)ethane], and the trimetallic[(C 6 F 5 ) 2 Ni(μ‐NCS) 2 Pd(μ‐SCN) 2 Ni(C 6 F 5 ) 2 ] 2– . The mononuclear compounds [(C 6 F 5 ) 2 NiLX] (L = PPh 3 , P(C 6 H 4 MeO‐ p ) 3 ; X = SCN, OCN) are obtained by reaction between [(C 6 F 5 ) 2 Ni(&μ‐X) 2 Ni‐(C 6 F 5 ) 2 ] 2– and L. The treatment of cis‐ [Ni(C 6 F 5 ) 2 (PhCN) 2 ] with [M(SAr) 2 (dppe)] leads to the formation of the arylthiolate complexes [(C 6 F 5 ) 2 Ni(μ‐SAr) 2 M(dppe)] (Ar = Ph, C 6 H 4 Me‐ p , C 6 H 4 NO 2 ‐ p ; M = Ni, Pd, Pt). The X‐ray diffraction study of [(C 6 F 5 ) 2 Ni(μ‐SPh) 2 Pd(dppe)] shows that both metal atoms, Ni and Pd, are coordinated in a slightly distorted square‐planar geometry and the μ‐thiolato groups are in the syn conformation.
