Mo（W）－Cu（Ag）－S原子簇化合物的研究现状

STUDIES OF Mo(W)-Cu(Ag)-S CLUSTER COMPOUNDS

本文在研究Ｍｏ（Ｗ）－Ｃｕ（Ａｇ）－Ｓ原子簇化合物的低热固态合成化学基础上，详细地对该类簇合物进行了归纳，从中提出：１．（Ｍ＝Ｍｏ，Ｗ；ｎ＝２，３，４）作为配体中心．２．氧原子在簇合物中仅作为端基，不参与同其他金属成键．３．单个ＭＳ４（Ｍ＝Ｍｏ，Ｗ）基团最多只能键合六个Ｃｕ（Ａｇ）原子，即最大核数为七．４．迄今为止所有Ｍｏ（Ｗ）－Ｃｕ－Ｓ原子簇化合物中Ｃｕ均为＋１价．５．预计合低价态Ｍｏ（Ｗ）的这类簇合物将会有很大进展．

On the basis of studying the low-heating solid state synthesis of Mo(W)-Cu(Ag)-S cluster compounds, we systematically classify this kind of clusters and propose several suggestions,which might be useful for further research.1. In Mo(W)-Cu(Ag)-S clusters, can be regarded as coordination center.2. Oxygen atoms only act as terminal group.3. Single MS4 moiety can form dinuclear, trinuclear, tetranuclear, pentanuclear,hexanuclear, heptanuclear step by step when it coordinates with Cu(Ag) atoms.4. Using lower valence Mo(W), we may synthesize new framework clusters with higher nuclearity.
