The ferrocenyl‐substituted mono‐ ( 3 ) and 1,1′‐bis‐dithiocarboxylic acids ( 4 ) have been prepared. These acids react with L 2 MCl 2 (M = Pd, Pt; L = PEt 3 , PPh 3 , and 1/2 dppe) in the presence of sodium acetate to give the cis heterodi‐ and heterotrimetallic complexes cis ‐L 2 M[S 2 CCHC(O)–(η 5 ‐C 5 H 4 )Fe(η 5 ‐C 5 H 5 )] ( 5a : M = Pd, L = PPh 3 ; 5b : M = Pt, L = PPh 3 ; 5c : M = Pt, L = 1/2 dppe) and [ cis ‐L 2 MS 2 C = CHC(O)‐(η 5 C 5 H 4 )] 2 Fe ( 6a : M = Pd, L = PPh 3 ; 6b : M = Pt, L = PEt 3 ; 6c : M = Pt, L = PPh 3 ; 6d : M = Pt, L = 1/2 dppe). The structures of 5a and 5b have been determined by single‐crystal X‐ray diffraction.
