[Mo_2FeS_8O_2][Et_4N]_3·CH_3CN晶体属三斜晶系,PI空间群.α=9.998(1)A,b=13.868(3)A,c=16.796(3)A,α=74.66(2)°,β=85.41(1)°,ν=72.21(1)°,Ζ=2.结构参数经块矩阵最小二乘法精修后,最后的偏离因子R=0.037,R_w=0.034.平均键长Mo—Fe为2.722A,Mo—S为2.358A,Fe—S为2.244A,Mo—O为1.697A.结果表明:标题化合物是一个结构新颖的原子簇化合物.它是由一个三价原子簇阴离子与三个一价的乙基季铵阳离子靠静电引力结合在一起,又溶剂合一个乙氰分子的原子簇化合物而形成.
The crystal of [Mo_2FeS_8O_2] [Et_4N] _3 · CH_3CN belongs to the triclinic system with the space group of PI, α = 9.998 (1) A, b = 13.868 (3) A, c = 16.796 (3) A, °, β = 85.41 (1) °, ν = 72.21 (1) °, Z = 2. The final deviation factor R = 0.037 and R_w = 0.034 after the structural parameters were refined by the least square method of block matrix. -Fe is 2.722 A, Mo-S is 2.358 A, Fe-S is 2.244 A, Mo-O is 1.697 A. The results show that the title compound is a novel atom cluster compound which consists of a trivalent atomic cluster anion With three monovalent ethyl quaternary ammonium cations by electrostatic attraction together, but also solvate a cyanide molecule cluster compounds formed.
