三间乙氧苯基铋的合成及晶体结构

Preparation and crystal structure of tri(m-ethoxyphenyl)bismuthine

利用相转移催化法得到了间溴苯乙醚,再通过相应的格氏试剂与三氯化铋反应合成了标题化合物,在乙醇和乙醚的混合溶剂中培养出单晶,并通过X射线单晶结构分析法测定了分子结构和晶体结构。晶体属于正交晶系,P212121空间群,晶胞参数为:a=0.6314(2)nm,b=1.5011(4)nm,c=2.3808(6)nm,V=2.2566(9)nm3,Dc=1.685g/cm3,μ=7.833mm-1,F(000)=1112,Z=4,R1=0.0457,wR2=0.0962。

Tri （m-ethoxyphenyl） bismuthine was synthesized by mixing the Grignard reagent with trichlorobismuthine. The structure of the target compound was characterized by elemental analysis and IR spectroscopy. The crystal structure was determined by the X-ray, diffraction method. Its crystals belonged to the orthorhombic system with a space group of P212121 and the following cell parameters：α = 0.631 4（2） nm, b = 1.501 1（4） nm, c = 2.380 8（6） nm, V= 2.256 6（9） nm^3, Dc = 1.685 g/cm^3, μ=7.833 mm^-l, F（000） = 1 l12,Z =4,R1 =0.045 7,and ωR2 = 0.096 2.
