摘要
用固相反应法合成了半胱氨酸与碘化砷、氯化锑、碘化锑、氯化铋、碘化铋的配合物 ,其组成为 :ML3X3(M =As、Sb、Bi,L =Cys ,X =I、Cl) ,通过XRD谱的研究说明配合物的形成。这些配合物在空气中稳定 ,不吸湿 ,微溶于水。As(Cys) 3I3配合物的晶胞参数为 :a=1.1743nm ,b =0 .6945nm ,c=1.682 2nm ,β =95 .2 8° ,V =1.3 661nm3;Sb(Cys) 3Cl3配合物的晶胞参数为 :a =1.2 0 5 1nm ,b =0 .6792nm ,c =1.685 0nm ,β =95 .79° ,V =1.3 72 1nm3。
Complexes of cysteine with antimony (Ⅲ), arsenic(Ⅲ) and bismuth(Ⅲ) were synthesized by solid solid phase reaction and characterized by X ray powder diffraction. The complexes had the composition of ML 3X 3(M=As,Sb,Bi;L=Cys;X=I?Cl),which were stable at room temperature,non hygroscopic and slightly soluble in water.Indexes of the X ray powder diffraction data also indicated that crystal structures of these complexes belonging to monoclinic system,with lattice parameters:a 1.2051 nm,b 0.6792 nm,c 1.6850 nm, β 95.79°,and V 1.3721 nm 3 for Sb(Cys) 3Cl 3;and a 1.1743 nm, b 0.6945 nm, c 1.6822 nm, β 95.28°,and V 1.3661 nm 3 for As(Cys) 3I 3 respectively.
