Two new coordination polymers {[Ag(bpe)]₄V₆O₁₇}_n (1) and {[Ag(bpe)]₁₀V₁₄O₄₀}_n∙3nH₂O (2) (bpe = 1,2-di(4-pyridyl)ethylene) had been synthesized by hydrothermal methods, and characterized by elemental analysis, IR, UV-vis, TG, XRD and single-crystal X-ray diffraction. Structural analysis revealed that they both consist of {VO₄}-based chain-like polyanions and {Ag-bpe} cationic units. The structural differences of 1–2 clearly showed that the polyoxovanadates are sensitive to the dosages of NH₄VO₃ source in synthesis reaction. The aromatic π…π stacking and Ag…Ag weak interactions among {Ag-bpe} cationic units contribute the significant effect on the stability of 3D crystal structures. The catalytic properties of the synthesized crystals were tested. It was found that the photochemical degradation of MB can reach 74.2% in 90 min by using 1 as catalyst.

两种新的配位聚合物{[Ag（bpe）] ₄ V ₆ O ₁₇ } _n（1）和{[Ag（bpe）] ₁₀ V ₁₄ O ₄₀ } _n ∙3nH ₂ O（2）（bpe = 1,2-通过水热法合成了二（4-吡啶基）乙烯，并通过元素分析，红外，紫外-可见，TG，XRD和单晶X射线衍射进行了表征。结构分析表明它们均由基于{VO ₄ }的链状聚阴离子和{Ag-bpe}阳离子单元组成。1-2的结构差异清楚地表明，聚氧钒酸盐对NH ₄的剂量敏感合成反应中的VO ₃源。{Ag-bpe}阳离子单元之间的芳族π…π堆积和Ag…Ag弱相互作用对3D晶体结构的稳定性有重要影响。测试了合成晶体的催化性能。 通过使用1作为催化剂，发现MB在90min内的光化学降解率可达到74.2％。
