Abstract

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)₂(η²-CS ₂)] (R = Et or Ph) leads to the formation of the bimetallic complexes [(PR₃)₂(CO)₂Fe(μ-η ²:η¹-CS₂)M(CO)₅]. Photolysis of acetonitrile solutions of [Os₃(CO)₁₂] with [Fe(CO)₂(PR₃)₂(η²-CS ₂)] leads to [(PR₃)₂(CO)₂Fe(μ-η ²:η¹-CS₂)Os₃(CO)₁₁]. Photolysis of a thf solution of (PEt₃)₂(CO)₂Fe(μ-η ²:η¹-CS₂)M(CO)₅] with PEt₃ results in the formation of the phosphine-substituted complex [(PPh₃)₂(CO)₂Fe(μ-η ²:η¹-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 ²:η¹-CS₂)W(CO)₅], [(PEt₃)₂(CO)₂Fe(μ-η ²:η¹-CS₂)Os₃(CO)₁₁] and [(PPh₃)₂(CO)₂Fe(μ-η ²:η¹-CS₂)Cr(CO)₄(PEt ₃)].
