摘要：

Treatment of [Os5H4(CO)11(eta6-C6H6)] 1 with 1,8-diazabicyclo[5.4.0]undec-7-ene in CHCl2 gives the dianion [Os5H2(CO)11(eta6-C6H6)]2- 2, and subsequent reaction of 2 with [Os(eta6-C6H6)(MeCN)3][BF4]2 provides the new bis-benzene cluster [Os6H2(CO)11(eta6-C6H6)(mu3-eta2:eta2:eta2-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 eta6 site and the other in a face-capping mu3-eta2:eta2:eta2 site.
