Ferrocenesuccinate-bridged lanthanide polymeric complexes: Syntheses, structures and properties

One-dimensional lanthanide-ferrocenesuccinate isomorphous polymers [M(η2-FcCOC2H4COO)(μ2-η2-FcCOC2H4COO)2(H2O)2]n (Fc = (η5-C5H4)Fe(η5-C5H4), M = Pr, 1; M = Ce, 2; M = La, 3) were synthesized and structurally characterized. Polymers 1 and 2 both display weak antiferromagnetic interaction. The redox properties are different from the previous results of transition metal compounds containing ferrocenyl systems. Compared with sodium ferrocenesuccinate, polymers 1 and 3, the fluorescent intensities of 2 are markedly enhanced in the solid state.
