Catena-Poly[[aqua-(dipyrido[3,2-a:2',3'-c]phenazine-?N,N)iron(II)]-?-pyrazine-2,3-dicarboxyl-ato-?N,O:O].

ABSTRACT: In the title compound, [Fe(C(6)H(2)N(2)O(4))(C(18)H(10)N(4))(H(2)O)](n), the Fe(II) ion adopts a slightly distorted octahedral mer-FeN(3)O(3) geometry, arising from one N,N'-bidentate dipyrido[3,2-a:2',3'-c]phenazine ligand, one N,O-chelating pyrazine-2,3-dicarboxyl-ate dianion and one water mol-ecule. An O-bonded symmetry-related dianion completes the coordination of the metal. The bridging dianion results in a one-dimensional polymeric chain. Aromatic ?-? stacking inter-actions between ligands [centroid-centroid separations = 3.528?(2) and 3.741?(2)?Å] and O-H?O and O-H?N hydrogen bonds link the chains together, leading to a three-dimensional supra-molecular network.
