【摘要】 用Ru3(CO)12和双(硫代磷酸二异丙基酯)二硫化物(C3H7-i-O)2P(S)-S-S-P(S)(O-i-C3H7)2反应得到一个新的含羰基钌配位化合物Ru(CO)2[S2P(O-i-C3H7)2]2,对其进行了元素分析和IR(υco)、1HNMR、31PNMR及MS谱学表征,并测定了分子的晶体结构,属于单斜晶系,C2/c空间群,晶胞参数:a=2.4608(1)nm,b=0.91372(6)nm,c=1.21461(5)nm,α=90°,β=109.609°,γ=90°,Z=4,V=2.5726(2)nm3,Dc=1.509g/cm-3,μ=1.082mm-1,F(000)=1192,(Δρ)max=377e·nm-3,(Δρ)mix=-602e·nm-3,R=0.0269,wR2=0.0522.晶体结构分析表明,该配合物的分子骨架RuS4C2近似为八面体结构,由两个螯合配体S2P(O-i-C3H7)2提供的4个硫原子和2个端羰基CO配体与中心原子钌成键,分子内含有两个等价的平面四元环RuSPS组件.更多还原

【Abstract】 A new ruthenium carbonyl complex Ru（CO）₂[S₂P（O-i-C₃H₇）₂]₂ was synthesized by reaction of Ru₃（CO）₁₂ with （C₃H₇-i-O）₂P（S）-S-S-P（S）（O-i-C₃H₇）₂.This complex was characterized by elementary analysis,IR(υ_co),¹H NMR,³¹P NMR and MS spectroscopy,and its crystal structure was determined by X-ray single crystal diffraction method.The crystal belongs to monoclinic,space group C 2/c,with crystal parameters as follows:a=2.4608（1） nm,b=0.91372（6） nm,c=1.21461（5） nm,α=90°,β=109.609°,γ=90°,Z=4,V=2.5726（2） nm³,Dc=1.509 g/cm^-3,μ=1.082 mm^-1,F（000）=1192, （Δρ）_max=377 e·nm^-3,（Δρ）_mix=-602 e·nm^-3,R=0.0269,（wR₂=0.0522）.The structural analysis shows that the molecular framework,Ru S₄C₂,is approximately octahedral,where the four sulfur atoms from two chelate ligands（C₃H₇-i-O）₂PS₂ and two carbonyls as terminal ligands link with a ruthenium atom.The molecular contains two equivalent four member plane rings of RuSPS.更多还原
