The new redox active coordination polymer [Cd(H₂O)₂(fc(PHOO)₂)·2H₂O]_n (fc = 1,1′-ferrocenediyl) was synthesized and structurally characterized by single-crystal X-ray diffraction. In this compound cadmium atoms are bound by phosphinate fragments to give infinite chains, the latter are interconnected by ferrocene groups to form 2D coordination polymer. Electrochemical properties of CP were investigated. It's found that Cd-polymer is harder to oxidize than its isostructural cobalt analogue. This means that increase in the length of the M − O bond in coordination polymer, oxidation becomes harder.

聚（1,1'-二茂铁基镉双（H-次膦酸酯））的合成，晶体结构和电化学性能

合成了新型氧化还原活性配位聚合物[Cd（H ₂ O）₂（fc（PHOO）₂）·2H ₂ O] _n（fc = 1,1'-二茂铁基），并通过单晶X射线衍射对其结构进行了表征。 。在该化合物中，镉原子与次膦酸酯片段结合形成无限链，后者通过二茂铁基团相互连接形成2D配位聚合物。研究了CP的电化学性能。发现镉聚合物比其同结构的钴类似物更难氧化。这意味着配位聚合物中M-O键的长度增加，氧化变难。
