这一类的特征已经由几个X射线模具定义。由于起始材料不包含金属-金属结合，一个自然的问题是金属三角形是如何(为什么以及何时)组装的？显然，Cpm(C0)(M=Co，10Rh，‘L Ir12)的生成允许形成三聚体Cp，M~(CO)~(12)。因此，在L所示的反应所需的条件下，金属三聚体可以在溶液中预组装并作为拆解炔烃的模板似乎是合理的。在三核炔烃络合物中存在两种已建立的炔烃环化模式：l~构型11
features of this class have been defined by several X-ray st~dies.~~~~~~ Since the starting material contains no metal-metal bonding, a natural question is how (why and when) does the metal triangle assemble? Apparently, generation of CpM(C0) (M = Co,l0 Rh,'l Ir12) allows formation of the trimer CP,M~(CO)~. It therefore seems reasonable that under the conditions necessary for the reaction shown in (l), metal trimers may preassemble in solution and serve as templates for the dismantling of an alkyne. In a trinuclear alkyne complex there are two established modes of alkyne c00rdination.l~ Configuration 11, exem
