A new layered zirconium phosphate |Co(dien)(2)|[Zr(4)H(8)P(5)O(26)] x 3H(2)O (denoted ZrPO-CJ37) has been synthesized hydrothermally by using a racemic mixture of a chiral cobaltammine complex Co(dien)(2)Cl(3) as the template. Its structure is determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, inductively coupled plasma, thermogravimetric, UV-vis, and photoluminescence analyses. The inorganic layer of ZrPO-CJ37 is built up from the linkage of Zr-centered octahedra and P-centered tetrahedra via vertex oxygen atoms forming a 4.6-net sheet. Its structure features the edge-sharing chains of Zr(OM)(6) (M = P, H) octahedra. The cobaltammine complex cations are located in the interlayer region and interact with the host network through H bonds. ZrPO-CJ37 exhibits interesting photoluminescence in the UV-vis spectral region. The edge-sharing chains of Zr(OM)(6) octahedra in the inorganic layer might be responsible for this unusual photoluminescence.
一种新型层状磷酸锆|[Co(dien)(2)]|[Zr(4)H(8)P(5)O(26)]·3H(2)O（记为ZrPO-CJ37）已通过使用手性钴胺配合物Co(dien)(2)Cl(3)的外消旋混合物作为模板进行水热合成。其结构通过单晶X射线衍射分析确定，并通过X射线粉末衍射、电感耦合等离子体、热重、紫外可见和光致发光分析进一步表征。ZrPO-CJ37的无机层由以Zr为中心的八面体和以P为中心的四面体通过顶点氧原子连接而成，形成一个4.6网层。其结构特征是以Zr(OM)(6)（M = P，H）八面体的边共享链。钴胺配合物阳离子位于层间区域，并通过氢键与主体网络相互作用。ZrPO-CJ37在紫外可见光谱区域表现出有趣的光致发光。无机层中Zr(OM)(6)八面体的边共享链可能是这种异常光致发光的原因。
