catena-Poly[[[tetraaquacobalt(II)]--4,4'-bipyridine-²N:N'] bis(perchlorate) 4,4'-bipyridine disolvate dihydrate]

J. H. Nettleman and R. L. LaDuca

Abstract: In the title compound, {[Co(C₁₀H₈N₂)(H₂O)₄](ClO₄)₂·2C₁₀H₈N₂·2H₂O}_n, slightly distorted octahedrally coordinated Co^II 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.
