Poly[[[diaquacobalt(II)]-bis[μ2-1,1′-(butane-1,4-diyl)diimidazole-κ2N3:N3′]] dichloride tetrahydrate]

In the title compound, {[Co(C10H14N4)2(H2O)2]Cl2·4H2O}n, the CoII atom and the mid-point of the 1,1′-butane-1,4-diyldiimidazole ligands lie on inversion centers. The CoII 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 CoII 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.
