近十年来,异核金属羰基簇(heteronuclear metal carbonyl clusters或mixed-metal carbanyl dusters,以下简称异核簇)有了很大的进展。这不仅是由于异核簇的合成在结构化学上的意义,而且它在以下三个方面对催化研究有其特殊的作用。其一,异核簇可作为研究双金属或多金属多相催化剂表面的模型,推动对合金催化剂认识的深化;其二,利用异核簇可制备出具有 Over the past decade, heteronuclear metal carbonyl clusters (mixed-metal carbanyl dusters, hereinafter referred to as heteronuclear clusters) have made great progress. This is not only due to the structural chemical significance of the synthesis of heteronuclear clusters, but also has a special role in catalytic research in the following three aspects. First, heteronuclear clusters can be used as a model for studying the surface of bimetallic or multimetallic heterogeneous catalysts to promote the deepening understanding of the alloy catalysts. Second, the use of different nuclear clusters can be prepared with
