Synthesis, Crystal Structure and Electrochemical Property of a One-dimensional Chain Pb(Ⅱ) Coordination Polymer Constructed from 3-Ferrocenylcrotonic Anion and 1,10-Phenanthroline

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=(η5-C5H5)Fe(η5-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.
