Abstract

In the title compound, [Co(C(6)H(2)N(2)O(4))(C(14)H(8)N(4))(H(2)O)](n), the Co atom is bonded to one N,N'-bidentate pyrazino[2,3-f][1,10]phenanthroline (Pyphen) ligand, one N,O-bidentate pyrazine-2,3-dicarboxyl-ate (PZDC) dianion and one water mol-ecule in a distorted octa-hedral mer-CoN(3)O(3) geometry. The Co(II) atoms are bridged by the PZDC dianions, forming an infinite one-dimensional chain running along the b axis. Adjacent chains pack together through π-π stacking inter-actions [centroid-centroid separations = 3.498 (4) and 3.528 (4) Å], and O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecule complete the structure.
