Abstract

Treatment of [Os₅H₄(CO)₁₁(η⁶-C ₆H₆)] 1 with 1,8-diazabicyclo[5.4.0]undec-7-ene in CH₂Cl₂ gives the dianion [Os₅H₂(CO)₁₁(η⁶-C ₆H₆)]^2- 2, and subsequent reaction of 2 with [Os(η⁶-C₆H₆)(MeCN)₃][BF ₄]₂ provides the new bis-benzene cluster [Os₆H₂(CO)₁₁(η⁶-C ₆H₆)(μ₃-η²:η ²:η²-C₆H₆)] 3 in ca. 35% yield, the X-ray analysis of which shows that the six osmium atoms adopt a bicapped tetrahedral geometry with one benzene ligand in a terminal η⁶ site and the other in a face-capping μ₃-η²:η²:η² site.
