title: [Ln2(C2O4)2(pyzc)2(H2O)2]n[Ln = Pr (1), Er (2)]: novel two-dimensional lanthanide coordination polymers with 2-pyrazinecarboxylate and oxalate.
abstract: We report for the first time hydrothermal synthesis of lanthanide-pyzcH polymers, [Ln2(C2O4)2(pyzc)2 (H2O)2]n [Ln = Pr (1), Er (2)], in which pyzcH was decomposed into C2O42- and thus caused novel two-dimensional hexagonal lattice networks. The magnetic property of polymer 1 has been studied by an approximate treatment being enlightened by McPherson et al. (Inorg. Chim. Acta 1988, 148, 265), leading to Delta = -4.3 cm-1, zJ' = -11.73 cm-1, and g = 0.79. Complex 2 displays an intense room-temperature, liquid-state luminescent emission.
