Abstract
[MO_3S_7Cl]结构单元钼-硫簇合物的晶体结构王曼芳,郭国聪(厦门大学化学系)(中科院福建物质结构研究所)含MO_3(μ_3-X)和MO_3(μ_3-X)_2(X=O,S)的三核钼族合物,在考虑簇骨架多面体时可认为金属与非金属混合组成的结构多面... The title cluster compound Mo3S_7Cl(dtc)_3·S_8· 2CH_2Cl_2 was synthesized bymeans of solid state reaction at low heating temperature, with monoclinic structure:P2_1 /n,a= 1 1 780(6),b=1.5 524(4),c=2.600(6)nmMr= 1412.77,V= 4.696(nm) ̄3,Z= 4,Dc=2.00 g/cm ̄3,F(000)=2792,μ(MoKa )=19. 81 cm ̄(-1),Final R= 0.067,Rw= 0.074 For 2545 u-nique observed reFlections(I≥3σ(I)).The three Mo atoms Form an equilateral triangle with Mo-Mo average bond length 0.2 716 nm,and three S-Cl average bond length 0.3 068 nm.
