摘　　要：以[Et_4N]_2MoS_4,Fe(CO)_5为原料合成出标题簇合物晶体,用X-射线单晶衍射方法测定了其晶体结构,晶体属于P2_1/n空间群,晶胞参数为α=0.9497(1)nm,b=1.3802(1)nm,c=1.1880(1)nm,β=112.8.°,经块矩阵最小二乘法精修所有结构参数,最终得偏离因子R=0.057,并对簇合物的红外光谱和紫外可见光谱进行了研究。The crystal of (Et_4N)_2[Fe_2(CO)_8] cluster was prepared with (Et_4N)_2MoS_4, Fe(CO)_5 as starting material, and the crystal structure was determined by X-ray diffraction. The cluster compound crystallized in the monoclinic space group P2_1/n with the unit cell parameters: a=0. 9497(1) nm, b=1. 3802(1) nm, c=1. 1880(1) nm, β=112.81°, 1=1. 4354(2) nm^3, Z=2. The block least-square refinement for all structure parameters gave final discrepancy factor R=0.057, and the IR, UV-visible spectra of cluster compound had been studied.
