Abstract

Hydrothermal reaction of fumaric acid and isonicotinic acid in presence of trace quantity of nitric acid produced an unprecedented two-dimensional coordination polymer Eu(OOC-C5H4N-CH2-CH2-COO)(OOC-COO)·2H2O containing in situ formed new ligands, 3-(4-pyridinecarboxylate)propionic acid (inpro) and oxalate (ox) moieties. The formation of inpro ligand from isonicotinic acid and fumaric acid is presumably through dehydration between 3-hydroxylpropionic acid and 4-carboxypyridinium moieties present under the above conditions, and the oxalate formation due to the reductive coupling of CO2 radicals generated from 2-hydroxysuccinic acid through C-C bond cleavage. The compound crystallizes in monoclinic P21/C space group and contains nine-coordinated Eu3+ ion having a distorted mono-capped square-antiprismatic geometry. While two chelatively bridging oxalate moieties coordinating through four of their O atoms lead to the formation of zigzag Eu(III)-oxalate chains, four uniquely bridging anionic inpro ligands which coordinate through five O centers altogether make the system take an overall two-dimensional network arrangement. Upon excitation at 359 nm the compound exhibits interesting luminescent properties in solid state with several intense bands in the visible region; the most intense and sharp emission being in the red region at 615 nm due to 5D0 7F2 transition, facilitated by the low-symmetry coordination environment around Eu3+ ion by the ligands.
