Abstract

Title full: Synthesis of bridged and linked ruthenium and osmium carbonyl clusters containing a [Au₂(Ph₂PCH₂CH₂PPh₂)]²⁺ unit. The crystal and molecular structures of Ru₅C(CO)₁₄Au₂(Ph₂PCH₂CH₂PPh₂) and {Os₄H₃(CO)₁₂}₂Au₂ (Ph₂PCH₂CH₂PPh₂). Treatment of Au₂(Ph₂PCH₂CH₂PPh₂)Cl₂ with one equivalent of the [Ru₅C(CO)₁₄]^2- dianion in the presence of TlPF₆ gives Ru₅C(CO)₁₄Au₂(Ph₂PCH₂CH₂PPh₂) (1) in good yield and the [{Ru₅C(CO)₁₄}₂Au₂(Ph₂PCH₂CH₂PPh₂)]^2- (2) anion in low yield. Complex 2 becomes the major product if 2 equivalents of [Ru₅C(CO)₁₄]^2- are used. Reaction of [Au₂(Ph₂PCH₂CH₂PPh₂)Cl₂] with 3 equivalents of [H₃Os₄(CO)₁₂]^- anion in the presence of TlPF₆ affords {H₃Os₄(CO)₁₂}₂Au₂ (Ph₂PCH₂CH₂PPh₂) (3) in reasonable yield. X-ray diffraction studies of 1 and 3 show that they contain the [Au₂(Ph₂PCH₂CH₂PPh₂)]²⁺ fragment in different coordination modes.
