双核Mo-Fe-S原子簇配合物[Fe(2,2′-bpy)_3][S_2MoS_2FeCl_2],是(Et_4N)_2MoS_4、FeCl_2和2,2′-联吡啶在乙腈中反应得到的结晶化合物.晶体属单斜晶系,空间群P2_1/c;a=9.328(3),b=26.788(2),c=13.764(3)(?);β=95.38(3)°;V=3424.2(11)(?)~3;Z=4;D_c=1.698g/cm~3;F(000)=1752.晶体结构用直按法解出;经全矩阵最小二乘法修正,最后R=0.068,R_ω=0.071(3933个I>3(?)(I)的独立衍射).在晶体结构中配位阴离子[S_2MoS_2FeCl_2]~(2-)是排布在阳离子[Fe(2,2′-bpy)_3]~(2+)所形成的空腔中.它是以非统计分布的形式存在,从而较准确地测定了各项键参数.Mo…Fe距离为2.773(2)(?),Mo-S_b和Fe-S_b有大致相等的键长.
The binuclear Mo-Fe-S clusters [Fe (2,2’-bpy) _3] [S_2MoS_2FeCl_2] are the crystalline compounds obtained by the reaction of (Et_4N) _2MoS_4, FeCl_2 and 2,2’-bipyridine in acetonitrile. The crystals are monoclinic with space group P2_1 / c; a = 9.328 (3), b = 26.788 (2), c = 13.764 (3) (?) ~ 3; Z = 4; D_c = 1.698g / cm ~ 3; F (000) = 1752. The crystal structure was solved by straight-line method and corrected by full matrix least squares method. Finally, R = = 0.071 (3933 I> 3 (?) (I)). In the crystal structure, the coordination anions [S_2MoS_2FeCl_2] ~ (2-) are arranged in the cation [Fe (2,2’-bpy) ] ~ (2+) .It exists in the form of non-statistical distribution, so that the key parameters can be accurately measured. The Fe ... Fe distance is 2.773 (2) (?), Mo- S_b And Fe-S_b have approximately equal bond length.
