catena-Poly[[[tetra­aqua­cobalt(II)]-μ-4,4′-bipyridine-κ2N:N′] bis­(perchlorate) 4,4′-bipyridine disolvate dihydrate]

In the title compound, {[Co(C10H8N2)(H2O)4](ClO4)2·2C10H8N2·2H2O}n, slightly distorted octa­hedrally coordinated CoII ions situated on inversion centers are linked into polycationic chains through 4,4′-bipyridine tethering ligands. These are connected into supra­molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol­ecules. A twofold inter­penetrated primitive cubic supra­molecular network is formed by the inter­action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4′-bipyridine mol­ecules.
