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
