摘要
通过三碘化锑和三碘化铋与硫脲间的室温固固反应合成了三碘化锑、三碘化铋的硫脲配合物 ,其组成通式为 :M(CS(NH2 ) 2 ) 3 I3 (M =Sb ,Bi) .两种配合物的晶体结构均属于单斜晶系 ,锑配合物Sb(CS(NH2 ) 2 ) 3 I3 的晶胞参数为 :a =1.4 772nm ,b=1.6 5 82nm ,c =2 .0 6 74nm ,β =90 .81°,铋配合物Bi(CS(NH2 ) 2 ) 3 I3 的晶胞参数为 :a =1.4 0 10nm ,b =2 .0 16 8nm ,c =2 .0 397nm ,β =90 .84° .
The solid thiourea complexes of antimony and bismuth triiodide were synthesized by a solid_solid reaction of antimony and bismuth triiodide and thiourea at room temperature. The formula of the complex is M(CS(NH 2) 2) 3I 3 (M=Sb, Bi). The crystal sturcture of the complexes belongs to monoclinic system and the lattice parameters are: a=1.4772 nm , b=1.6582 nm ,c=2.0674 nm , β=90.81° for Sb(CS(NH 2) 2) 3I 3; a=1.4010 nm , b=2.0168 nm , c= 2.0397 nm , β=90.84° for Bi(CS(NH 2) 2) 3I 3 respectively. The far_infrared spectra of the complexes reveal that the trivalent antimony or bismuth ion is coordinated by the nitrogen atom, not by the sulfur atom of the thiourea in the complexes.
