通过(η5-C5H5)2Fe2(C O)4和硒粉在沸腾的甲苯中反应可制得含μ3-Se的立方烷簇合物(η5-C5H5)4 Fe4(μ3-Se)4 (1)，而由(η5-RC5H4)2Cr2(CO )4S在甲苯中回流可制得含μ3-S的立方烷簇合物(η5-RC5H4)4Cr4(μ3 -S)4 (2,R＝COMe;3,R＝CO2Me)。企图通过(η5-EtO2CC5H4)2Fe2(CO)4 (5)和硫黄制备μ3-S立方烷簇合物(η5-EtO2CC5H4)4Fe4(μ3-S)4 ( 6)未获成功，其中5是由η5-EtO2CC5H4Fe(C O)2Na与η5-EtO2CC5H4Fe(CO)2I (4)缩合制得。新化合物1～5经元素分析，IR和1H NMR光谱表征。

A cubane-type cluster (η5-C5H5)4Fe4( μ3-Se)4 (1)was prepared by reaction of (η5-C5H5)2F e2(CO)4 with elemental selenium in refluxing toluene，whereas two cubane-ty pe clusters with a general formula (η5-RC5H4)4Cr4(μ3-S)4 (2, R＝COMe； 3, R＝CO2Me), were obtained by self-asse mb ly reaction of (η5-RC5H4)2Cr2(CO)4S in toluene at reflux. An attem pt to prepare cubane-type cluster (η5-EtO2CC5H4)4Fe4(μ3-S)4 was unsuccessful through reaction of elemental sulfur and (η5-EtO2CC5H 4)2Fe2(CO)4 (5) made from η5- EtO2CC5H4Fe(CO)2 Na and η5-EtO2CC5H4Fe(CO)2I (4). New compounds 1～5 have been characterized by elemental analysis, IR and 1H NMR spectroscopies.
