In this paper, the reports of [(C_4H_9) _4N] _3 [Fe (MoS_4) _2O], [(C_2H_5) _4N] _3 [Fe (MoS_4) _2O_2] and [(C_2H_5) _4N] _3 [Fe (MoS_4) Synthesis, Characterization and Characterization of Six Cluster Structures of [(C_4H_9) _4M] _2 [Mo_2S_6O_2], [(C_2H_5) _4N] _3 {[(SCH_2CH_2S) MoS_3] _2Fe} and [C_2H_5) _4N] _4 [Fe_6S_9 (SCH_2CH_2OH) Cl] Structure and properties of the study. The data were collected by CuK_a (MoK_a) radiation on a Nicolct R_3 system Siyuan single crystal diffractometer. The crystal structure of these clusters was solved by the SHELXTL program and the heavy atom method. The physical properties of the clusters were determined by IR, UV-Vis and Mossbauer spectroscopy. At the same time, the activity of reducing acetylene to ethylene in the presence of reducing agent KBH_4 was also measured. In addition, the relationship between the electronic structure and the properties of the cluster compounds was discussed in combination with quantum chemistry calculations.
