Pb(OAc)2•3H2O, 3-二茂铁-2-丁烯酸钠以及1,10-邻菲啰啉在甲醇中反应得到了铅的配位聚合物: [Pb(m-OOCCH=C(CH3)Fc)(m2-OOCCH=C(CH3)Fc)(phen)]n (Fc=(h5-C5H5)Fe(h5-C5H4); phen=1,10-邻菲啰啉). 单晶测试表明: 每个铅离子为六配位, 其中4个氧原子来自4个3-二茂铁-2-丁烯酸根, 另2个氮原子来自邻菲啰啉; 相邻的铅离子通过3-二茂铁-2-丁烯酸根的单齿和双齿氧原子桥连形成了一个无限的一维长链. 研究了标题化合物在DMF溶液中的电化学性能.

A novel coordination polymer [Pb(m-OOCCH=C(CH3)Fc)(m2-OOCCH=C(CH3)Fc)(phen)]n (Fc=(h5-C5H5)Fe(h5-C5H4); phen=1,10-phenanthroline) was obtained by the reaction of Pb(OAc)2•3H2O with NaOOCCH=C(CH3)Fc and phen in methanol solution. X-ray structural analysis reveals that each Pb(II) ion in the compound is in a six-coordinated geometry in which four oxygen atoms come from four Fc(CH3)C=CHCOO units, and two nitrogen atoms from the phen ligand. In its solid-state structure, Fc(CH3)C=CHCOO anion acts as m-mode or m2-mode bridging the central Pb(II) ions and thus forming a 1-D chain. The cyclic voltammetries of the title compound and the corresponding ferrocenyl ligand were investigated in DMF solution.

Key words: coordination polymer, lead(II), sodium 3-ferrocenylcrotonate, 1,10-phenanthroline, crystal structure, electrochemical property
