在中性水溶液中合成了Keggin型铜取代磷钨杂多阴离子PW11O39Cu(II)(H2O)5-(PW11Cu)，并对其进行IR、UV-Vis和循环伏安表征。实验结果表明，PW11Cu在700~1100 cm-1的指纹区内有四个特征振动吸收峰，分别对应于P-Oa、W=Od、W-Ob-W和W-Oc-W的反对称伸缩振动吸收。在200 nm和249 nm处有两个很强的紫外吸收，在650~800 nm的可见光区有一个较强的连续吸收带。循环伏安显示W-O骨架波和一对Cu的氧化-还原波。

Keggin-type Cu(II)-substituted heteropolyanion PW11O39Cu(II)(H2O)5-(PW11Cu) was synthesized in neutral aque?ous solution and characterized by IR, UV-Vis and cyclic voltammetry. Experimental results showed that in the 700-1100 cm-1 fingerprint area PW11Cu exhibits five characteristic absorption peaks, corresponding to the anti-symmetric stretching vibration of P-Oa, W=Od, W-Ob-W and W-Oc-W, respectively. There are two strong UV absorptions at near 200 nm and 249 nm and a continuous visible absorption band in the district of 650~800 nm for PW11Cu. In addition to W-O skele?ton-waves a pair of Cu(II)/Cu(I) redox wave appears in the cyclic voltammograms.
