摘　　要：本文报道了羰基异核原子簇,[(μ_2-S)HgFe_2Co(CO)_9(μ_3-Cl)]_2的合成及晶体结构.化合物由(μ_2-S)HgFe_2Co(CO)_9(μ_3-Cl)双聚而成.双聚分子具有c_(2h)对称性.在Fe—Fe,Fe—Co之间存在明显的金属一金属键.三核簇中的两个铁原子作为双齿配体与Hg原子配位.并通过HgS二聚形成双三角型簇合物.HgPe_2Co(CO)_9(μ_3-S) as a starting material was deprotonated and reacted with HgCl_2 to produce a carbonyl heteronuclear cluster, [(μ_2-S)HgFe_2Co(CO)_9(μ_3-Cl)]_2. In this paper, the cluster was characterized by IR, UV and Xray single crystal structure. It was formed by dipolymerization of (μ_2-S)HgFe_2Co(CO)_9(μ_3-Cl). Dipoling molecule have σ_(2h) symmetry. The Fe_2Co atoms are bridging with μ_3-Cl atom to form a trigonal pyramid cluster. There are apparent metal—metal bonds between the Fe—Fe and Fe—Co atoms. Both iron atoms of trinuclear cluster coordinated with Hg atom with bidentate. A double pyramidal cluster was formed by dipolymerization of HgS.
