A zinc-diphosphonate [Zn₂(HEDP)(L)]·2H₂O (1) was solvothermally prepared with L as a coligand (HEDP = 1-hydroxyethylidenediphosphonate, L = melamine). In 1, the {CPO₃} tetrahedral units in HEDP ligand bridge the Zn²⁺ ions through corner sharing to form [-Zn₂(HEDP)-]_n neutral chains as subunits, which are further cross-linked by neutral L moieties into a novel three dimensional (3D) hybrid framework. The compound was characterized by infrared (IR) spectroscopy, elemental analyses (EA), powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and fluorescence spectroscopy. Notably, compound 1 displays blue photoluminescence with an emission maximum at about 354 nm.

以L作为大分子配体（HEDP ＝ 1-羟基亚乙基二膦酸酯，L ＝三聚氰胺）溶剂热制备二膦酸锌[Zn ₂（HEDP）（L）]·2H ₂ O（1）。在图1中，HEDP配体中的{CPO ₃ }四面体单元通过角共享桥接Zn ²⁺离子以形成[-Zn ₂（HEDP）-] _n中性链作为亚基，并通过中性L部分进一步交联成一个新颖的三维（3D）混合框架。通过红外光谱，元素分析（EA），粉末X射线衍射（PXRD），热重分析（TGA）和荧光光谱对化合物进行表征。值得注意的是，化合物1 显示出最大约354 nm的蓝色光致发光。
