Poly[[[diaqua­cobalt(II)]-bis­[μ(2)-1,1′-(butane-1,4-di­yl)diimidazole-κ(2) N (3):N (3′)]] dichloride tetra­hydrate]

In the title compound, {[Co(C(10)H(14)N(4))(2)(H(2)O)(2)]Cl(2)·4H(2)O}(n), the Co(II) atom and the mid-point of the 1,1′-butane-1,4-diyl­diimidazole ligands lie on inversion centers. The Co(II) atom is six-coordinated in a slightly distorted octa­hedral environment by four N atoms from four different ligands and by two O atoms from the water mol­ecules. The Co(II) atoms are bridged by the ligands into a (4,4) net. Adjacent nets are linked to the chloride anions and uncoordinated water mol­ecules via O—H⋯Cl and O—H⋯O hydrogen bonds, generating a three-dimensional supra­molecular structure.
