本文报道了羰基异核原子簇, [(μ2-)HgFeCo(CO)~9(μ-CI)]~2的合成及晶体结构。化合物由(μ-S)HgFeCo(CO)~9(μ-CI)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-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。

HFe2Co(CO)9(m3-S) and was characterized by IR and UV spectra and single crystal x-ray diffraction. I consists of 2 trigonal pyramidal Fe2Co units with Fe-Fe and Fe-Co bonds and a bridging m3-Cl. Each Fe is coordinated to Hg and the dimeric unit is formed via bridging sulfides between Hg giving a C2h symmetry. Crystal data: orthorhombic, space group Pbam, a 1.4879(10), b 1.4965(8), c 1.4770(10) nm, Z = 4, R = 0.059, Rw = 0.056.
