| 摘 要： | Under anaerobic and water-free condition and pure dinitrogen atmosphere, the title com-pound has been synthesized from FeCl_2, (NH_4)_2WS_4, NaS_2CN(C_2H_5)_2 and (C_2H_5)_4NBr. Thecompound crystallizes in the monoclinic space group Cc with cell constants a = 22. 125(6)A,b = 11.313(3) A, c = 25.053(8) A, β= 118.05(2)°, V = 5534.2A~3, Z = 4. It contains cubane-like Fe_4S_4 core. Each Fe atom in the compound is coordinated by a disulfide-chelate ligand.The determination results of the Mossbauer spectrum arid XPS, and quantum-chemical cal-culation all show that the compound contains two kinds of Fe in different valence states butin an equal amount. The scheme of the formation reaction for the compound is given. Thespectra of IR and UV-vis, and redox properties for the compound are reported.
