摘要
本文介绍了国家自然科学基金重大项目“过渡金属原子簇化学研究”的意义、背景、研究内容和研究进展以及今后的设想。其中研究进展主要是:系统地研究了若干系列簇合物的反应规律,使“活性元件组装”由设想发展为合成方法;在国际上率先提出了[Mo_3S_3]^(6+)簇环体系中存在的类芳香性概念:在国际上首次合成及表征了数百种过渡金属同核及异核新簇合物(例如含钼、钨、铁、铜、钴、镍、钒及稀土等系列的新型簇合物);对钴、铒和铁羰基簇合物二元复合体系的双金属协同效应及稀土-过渡金属簇合物的新体系等的研究。
This paper presents the significance, background, substance, progress, and tentative idea in the studies on the chemistry of transition metal cluster compounds, which is one of the major projects supported by National Natural Science Foundation of China. Following advances have been made in this project:the 'unit construction' has been developed as one of the synthetic methods from systematic studies of the reactivities of a series of the transition metal cluster compounds; quasi-arornaticity of a kind of cluster compounds with [M3S3]6+ cores has first been advanced; more than three hundred new cluster compounds have been synthesized; the synergistic effect for bimetallic cluster compounds,such as cobalt,ruthenium,and iron carbonyl clusters,in the catalytic reactions and the solid state chemistry of rare-earth and other transition metal clusters have been studied.
