title: catena-Poly[[(1,3-dimethyl-imidazolin-2-one-κN)(1,10-phenanthroline-κ(2)N,N')copper(II)]-μ-furan-2,5-dicarboxyl-ato-κ(2)O(2):O(5)].
abstract: The polymeric title compound, [Cu(C(6)H(2)O(5))(C(12)H(8)N(2))(C(5)H(10)N(2)O)](n), is composed of an infinite chain formed along [100] by linking the (1,3-dimethyl-imidazolin-2-one)(1,10-phenanthroline)copper(II) units with two O atoms of two carboxyl-ate groups of the furan-2,5-dicarboxyl-ate ligand. The Cu(II) atom, which lies on a twofold rotation axis, displays a square-pyramidal coordination. The dihedral angles of the 1,10-phenanthroline ligand with respect to the furan rings of the carboxyl-ate anions that are connected to the metal atom are 62.18 (11) and 88.27 (12)°.
