Crystal structure and crystallography data of silver (Ag) co-ordinated thiourea single crystals

The silver (Ag) co-ordinated thiourea compounds I & II are reinvestigated, crystal structure refinements were done suitably. The crystalline materials belong to Triclinic and Tetragonal systems with a space group of P-1 and I41 respectively. In both the crystal systems, a single Ag atom co-ordinates with three thiourea ligands, and the chain is continued through Ag to Ag interactions. The structural properties like the strength of bond lengths and bond angles were studied by single-crystal X-diffraction technique.

本研究对银（Ag）配位硫脲化合物I与II进行了重新研究，并完成了恰当的晶体结构精修工作。该类结晶材料分别属于三斜晶系与四方晶系，对应的空间群依次为P-1与I41。在两种晶系中，单个银原子均与三个硫脲配体发生配位作用，链状结构通过银-银相互作用得以延伸。本研究通过单晶X射线衍射技术，对其键长、键角等结构特性及其强度特征展开了分析。
