摘要: 目前,Mo-S化合物的化学,特别是以多硫基为配体的铟硫化合物的化学是一个活跃的研究领域。这里我们报道含S22-、S42-两种多硫基的二核钼原子簇化合物〔Et4N〕2〔Mo2O2(S2)(S4)(u3-S)2]的合成和单晶结构。

Abstract: The compound (Et4N),(Mo2O2S8) has been synthesized, and its crystal and molecular structure have been determined. The compound crystallizes in orthor-hombic, space group D2h15-Pbcawith Z= 8. The cell dimensions are α= 13.197(4)Å, b=15.739(6)Å, c = 29.033 (6)Å, α=β=γ= 90°,V = 6030(3)Å3. The compound contains terminal oxygen ligand, persulfide group (S22-), tetrasul-fide group (S42-),and (μ-S)μ-sulfide group, and has a metal-metal bond (Mo-Mo distance 2.822(3)Å).
