Abstract The reaction between the acyl-substituted triosmium cluster [Os 3 H(CO) 10 (μ-COC 4 H 4 N)] and trimethylamine-N-oxide, at −78°C, yields not the expected pyrrole-linked cluster but the novel trimethylamine complex [Os 3 H(CO) 9 (NMe 3 )(μ-COC 4 H 4 N)] ( 1 ). An X-raycrystalstructure of the product shows that it consists of an η 2 -2-acylpyrrole bridged triosmium unit incorporating a terminally
摘要酰基取代的os簇[Os 3 H(CO)10(μ-COC4 H 4 N)]与三甲胺-N-氧化物在-78°C下的反应未产生预期的与吡咯连接的簇,但产生了新型三甲胺络合物[Os 3 H(CO)9(NMe 3)(μ-COC4 H 4 N)](1)。产物的X射线晶体结构表明,它由η2 -2-酰基吡咯桥联的tri单元组成,该单元掺入了在coordinate三角形的赤道位上的末端配位的三甲胺配体。
