Two new POMOF compounds, namely [PMo₁₂V₂O₄₂][Cu₃(4,4’-bpy)₃]·(DABCO) (1) and [PMo₁₀V₄O₄₂][Cu₂(4,4’-bpy)₂][Cu(phen)₂]₂ (2) (DABCO = triethylenediamine, bpy = bipyridine, phen = 1,10-phenanthroline)), have been synthesized and characterized by IR, UV–Vis, XRD, elemental analysis and X-ray diffraction analysis. Crystal structure analyses reveal that compounds 1 and 2 exhibit novel 2-D layered framework structures constructed from bi-capped Keggin molybdenum-vanadium polyoxoanions, metals and organic ligands, respectively. The main difference of the two compounds is that compound 2 contains both Cu²⁺ and Cu⁺ complexes. In addition, we also investigate the catalytic properties of the two compounds, both compound 1 and 2 are excellent catalysts for the epoxidation of styrene.

两种新的POMOF化合物，即[PMo ₁₂ V ₂ O ₄₂ ] [Cu ₃（4,4'-bpy）₃ ]·（DABCO）（1）和[PMo ₁₀ V ₄ O ₄₂ ] [Cu ₂（4,4 '-bpy）₂ ] [Cu（phen）₂ ] ₂（2）（DABCO =三亚乙基二胺，bpy =联吡啶，phen = 1,10-菲咯啉）），已通过IR，UV-Vis，XRD，元素分析和X射线衍射分析。晶体结构分析表明化合物1和2展示了分别由双封端的Keggin钼-钒聚氧阴离子，金属和有机配体构成的新型2-D层状骨架结构。两种化合物的主要区别在于化合物2同时包含Cu ²⁺和Cu ⁺配合物。此外，我们还研究了这两种化合物的催化性能，化合物1和2都是苯乙烯环氧化的优良催化剂。
