2-巯基-5-苯并咪唑磺酸（H_3MBZD）与Ag_2SO_4在溶剂热条件下反应生成了三维配位聚合物{Ag_5 [（H_2MBZD）_2（H_2MBZD）（H_2O）]}_n（1）。X-射线单晶分析表明，5个独立的Ag原子通过桥连巯基连接在一起，形成不对称的五核团簇，这些团簇结合在一起形成一个大的Ag 10环状亚基. Ag 10亚基通过-SO 3 H基团连接在一起，得到复杂的3D框架。1的强蓝色光致发光可以归因于配体内荧光发射。
The solvothermal reaction of 2-mercapto-5-benzimidazolesulfonic acid (H3MBZD), which has imidazole, –SH, and –SO3H groups, with Ag2SO4 led to the 3D coordination polymer {Ag5[(HMBZD)2(H2MBZD)(H2O)]} n (1). X-ray single-crystal analysis showed that five independent Ag atoms are connected by the bridging mercapto group to generate asymmetric pentanuclear clusters, which are joined together to form a large Ag10 ringed subunit. The Ag10 subunits are linked together by the –SO3H groups to give the complex 3D framework. Strong blue photoluminescence of 1 can be assigned to the intraligand fluorescent emission.
