Photochemistry has been used to generate a number of heterobimetallic complexes containing π + σ CS2 bridging groups. Broad-band UV photolysis of tetrahydrofuran (thf) solutions of [M(CO)6] (M = Cr, Mo or W) with [Fe(CO)2(PR3)22-CS 2)] (R = Et or Ph) leads to the formation of the bimetallic complexes [(PR3)2(CO)2Fe(μ-η 21-CS2)M(CO)5]. Photolysis of acetonitrile solutions of [Os3(CO)12] with [Fe(CO)2(PR3)22-CS 2)] leads to [(PR3)2(CO)2Fe(μ-η 21-CS2)Os3(CO)11]. Photolysis of a thf solution of (PEt3)2(CO)2Fe(μ-η 21-CS2)M(CO)5] with PEt3 results in the formation of the phosphine-substituted complex [(PPh3)2(CO)2Fe(μ-η 21-CS2)M(CO)4(PEt 3)]. Single-crystal X-ray diffraction has been used to determine the molecular structures of [(PPh3)2(CO)2Fe(μ-η 21-CS2)W(CO)5], [(PEt3)2(CO)2Fe(μ-η 21-CS2)Os3(CO)11] and [(PPh3)2(CO)2Fe(μ-η 21-CS2)Cr(CO)4(PEt 3)].
