Poly[[chloridodimethanol(μ(3)-pyridine-2,3-dicarboxyl-ato)europium(III)] methanol monosolvate]

The asymmetric unit of the title compound, {[Eu(C(7)H(3)NO(4))Cl(CH(3)OH)(2)]·CH(3)OH}(n), contains one Eu(III) ion, one pyridine 2,3-dicarboxylate dianion (PDC), two CH(3)OH mol-ecules coordinating to the metal atom, one coordinating chloride and one lattice occluded CH(3)OH mol-ecule. In the crystal, each PDC anion coordinates to three adjacent Eu(III) ions by the pyridine N and O atoms of the carboxyl-ate groups. The Eu(III) cation is eightfold coordinated by four carboxyl-ate 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).
