title: catena-Poly[[[aqua-(pyrazino-[2,3-f][1,10]phenanthroline-κN,N)zinc(II)]-μ-penta-nedioato] monohydrate].
abstract: In the title compound, {[Zn(C(5)H(6)O(4))(C(14)H(8)N(4))(H(2)O)]·H(2)O}(n), the Zn(2+) ion is coordinated by an N,N'-bidentate pyrazino-[2,3-f][1,10]phenanthroline (pyphen) ligand, a water molecule and a monodentate glutarate (glu) dianion. A symmetry-generated O:O'-bidentate glu dianion completes a distorted cis-ZnN(2)O(4) octa-hedral coordination geometry for the metal ion. The bridging glu species generates [110] polymeric chains in the crystal. O-H⋯O hydrogen bonds involving both the coordinated and uncoordinated water mol-ecules help to consolidate the structure and neighbouring pyphen units inter-act through numerous aromatic π-π inter-actions [minimum centroid-centroid separation = 3.654 (3) Å], resulting in a two-dimensional network.
