catena-Poly[[bis­[4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol]cadmium(II)]-μ-fumarato]

In the polymeric title compound, [Cd(C(4)H(2)O(4))(C(19)H(12)N(4)O)(2)](n), the Cd(II) centre is eight-coordinated within an N(4)O(4) donor set derived from two chelating 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol ligands and two asymmetrically chelating carboxyl­ate residues of bridging fu...

Sumario:In the polymeric title compound, [Cd(C(4)H(2)O(4))(C(19)H(12)N(4)O)(2)](n), the Cd(II) centre is eight-coordinated within an N(4)O(4) donor set derived from two chelating 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol ligands and two asymmetrically chelating carboxyl­ate residues of bridging fumarate dianions. The linear chains are linked into a layer in the ac plane via O—H⋯O(carboxyl­ate) hydrogen bonds. Layers are connected into double layers via N—H⋯O(carboxyl­ate) hydrogen bonds and these stack along the b axis. C—H⋯π inter­actions are also present. Disorder in the ethyl­ene portion of the fumarate was modelled over two positions, the major component having a site-occupancy factor of 0.677 (15).
