title: catena-Poly[[[aqua-(pyridine-2,6-dicarboxyl-ato N-oxide-κO,O)cobalt(II)]-μ-1,3-di-4-pyridylpropane-κN:N'] dihydrate].
abstract: In the title compound, {[Co(C(7)H(3)NO(5))(C(13)H(14)N(2))(H(2)O)]·2H(2)O}(n), the Co(II) atom is coordinated by two O atoms from a pyridine-2,6-dicarboxyl-ate N-oxide ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water mol-ecule, and displays a distorted square-pyramidal coordination geometry. The 1,3-di-4-pyridylpropane ligands link the Co(II) atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
