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)3I3(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)3I3的晶胞参数为:a=1.4772 nm,b=1.6582 nm,c=2.0674 nm,β=90.81°,铋配合物Bi(CS(NH2)2)3I3的晶胞参数为:a=1.4010 nm,b=2.0168 nm,c=2.0397 nm,β=90.84°. 远红外光谱表明硫脲中的N原子而非硫原子参与了配位.

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(NH2)2)3I3 (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(NH2)2)3I3; a=1.4010 nm, b=2.0168 nm, c=2.0397 nm, β=90.84° for Bi(CS(NH2)2)3I3 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.
