【Abstract】 In this paper, the synthesis, structure and properties of four type cluster compounds, (1) [Et4N]3[Mo2FeS6(SCH2CH2S)2] (2) [Et4N]3[W2FeS6(SCH2CH2S)2], (3) {[Et4N]3[Mo2FeS6(SCH2CH:S)2]}4·CH3CN and (4) [Et4N]4[Mo2Fe4S9(SCH2CH2S)J are reported. The crystal structure of these cluster compounds had been determined by X-ray method. The data of diffractional intensities of single crystals were obtained on a four-circle auto-diffractomer with MoKa radiation (Nicolet R3system) and the structure was worked out by the method of heavy atom using SHELXTL programme. The physical properties of these cluster compounds had been determined with IR, UV-Visible and Mossbauer spectra, simultaneously, the redox characteristics of these cluster componds had been studied with cyclic voltammetric method and the problem of electronic structure of these cluster compounds was discussed in combination with quantum-chemical calculations.更多还原
