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(μ-OOCCH=C(CH3)Fc)(μ2-OOCCH=C(CH3)Fc)(phen)]n(Fc=(η^5-C5H5)Fe(η^5-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(μ-OOCCH=C(CH3)Fc)(μ2-OOCCH=C(CH3)Fc)(phen)]n(Fc=(η^5-C5H5)Fe(η^5-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 μ-mode or μ2-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.
