catena-Poly[[[diaqua­cobalt(II)]bis­(μ-1,3-di-4-pyridylpropane-κ(2) N:N′)] bis­(perchlorate) bis­(1,3-di-4-pyridyl­propane) bis­(2-methyl-4-nitro­aniline)]

In the title compound, {[Co(C(13)H(14)N(2))(2)(H(2)O)(2)](ClO(4))(2)·2C(13)H(14)N(2)·2C(7)H(8)N(2)O(2)}(n), the Co(II) ion lies on a crystallographic inversion center and is coordinated by four N atoms from four symmetry-related 1,3-di-4-pyridylpropane ligands and two O atoms from two water ligands in a slightly distorted octa­hedral coordination environment. The 1,3-di-4-pyridylpropane ligands are doubly bridging and connect the Co(II) ions into one-dimensional chains. The asymmetric unit also contains one uncoordinated 1,3-di-4-pyridylpropane mol­ecule, one 2-methyl-4-nitro­aniline mol­ecule and one perchlorate anion. In the crystal structure, inter­molecular O—H⋯N hydrogen bonds connect the one-dimensional chains into a two-dimensional network.
