Poly[[chloridodimethanol(μ3-pyridine-2,3-dicarboxylato)europium(III)] methanol monosolvate]

Abstract

The asymmetric unit of the title compound, {[Eu(C7H3NO4)Cl(CH3OH)2]·CH3OH}n, contains one EuIII ion, one pyridine 2,3-dicarboxylate dianion (PDC), two CH3OH molecules coordinating to the metal atom, one coordinating chloride and one lattice occluded CH3OH molecule. In the crystal, each PDC anion coordinates to three adjacent EuIII ions by the pyridine N and O atoms of the carboxylate groups. The EuIII cation is eightfold coordinated by four carboxylate O atoms, one pyridine N atom, two MeOH and one chloride anion in the form of a distorted polyhedron. Extended coordination of the PDC ligand lead to the formation of a two-dimensional coordination polymer parallel to (10-1).
