the formation of compounds of the general formulae [Re(CO)3L2Br], [Re(CO)3L3]+ and [Re(CO)3L2L′], where L′ denotes a nido-carborane isonitrile ligand. The latter compound, whose structure was determined crystallographically, has an overall neutral charge as a result of a deboronation reaction which takes place upon recrystalization of the complex. We also observed that the ligand L has the ability to
3-异
氰基-1,2- dicarba- closo-十二
硼烷,否则被称为3-isonitrilecarborane(L)中,用[净发生反应4 ] 2 [的Re(CO)3
溴3 ]和[的Re(CO)3(SOLV 。)3 ] +以类似于脂肪族异腈的方式形成通式[Re(CO)3 L 2 Br],[Re(CO)3 L 3 ] +和[Re(CO) )3公升2L'],其中L'表示N-碳-碳烷异腈
配体。后一种化合物的结构由晶体学确定,由于配合物重结晶时发生脱
硼反应,因此具有总体中性电荷。我们还观察到,
配体L具有从[Re(CO)3(solv。)3 ] +取代CO
配体的能力,从而导致[Re(CO)2 L 4 ] +的形成。
