硫脲与含有立方硫代镉团簇([Cd8（SPhF-3)14(DMF)6]2+）的离子团簇化合物（记为CMM-5）在85℃的丙酮/水混合溶剂中发生溶剂热反应，将离散的立方团簇转化为共价连接的四面体团簇，作为具有α-石蜡型拓扑结构的螺旋化合物(记为CMF-8， [Cd8S（SC6H4F-3)12(SC6H4F-3)4/2]）的四面体节点。CMF-8在375 nm处有紫外-可见吸收，热分析表明它在300°C左右稳定。
Solvothermal reaction between thiourea and an ionic cluster compound (denoted CMM-5) containing a cubic cadmium thiolate cluster ([Cd8(SPhF-3)14(DMF)6]2+) at 85 °C in a mixed acetone/H2O solvent converts the discrete cubic cluster into the covalently linked tetrahedral cluster that serves as tetrahedral node in a helical compound (denoted CMF-8, [Cd8S(SC6H4F-3)12(SC6H4F-3)4/2]) with α-quartz-type topology. CMF-8 has a UV−vis absorption onset at 375 nm, and the thermal analysis shows that it is stable up to about 300 °C.
