Abstract

Treatment of ruthenium carbonyl, [Ru₃(CO)₁₂] with phenylseleno tribromide PhSeBr₃ afforded a new triruthenium cluster, [(CO)₁₀Br₄Ru₃(μ-SePh)₂] (1). Its molecular structure was determined by single crystal XRD method (P2 ₁/c; a = 10.514(3) Å ; b = 10.814(3) Å ; c = 19.063(5)Å ; β = 105.064(4)°; V = 2093.1(10)Å ³) and shown to have two lateral Ru(CO)₃Br₂ units attached via two PhSe bridges to a Ru(CO)₄ center forming a chain-like Ru-Se-Ru-Se-Ru cluster core. This is in contrast with a recently reported reaction of PhTeBr₃ with [Ru₃(CO)₁₂] which formed a monomeric complex of ruthenium-dicarbonyl-dibromo fragment coordinating two PhTeBr ligands, [(CO)₂RuBr₂(PhTeBr)₂].
