Crystal engineering of an inclusion coordination polymer with cationic pocket-like structure and its property to form metal–organic nanofibers

The reaction of cobalt nitrate hexahydrate with 4,4′-bipyridine (BPY) under hydrothermal conditions produced a new cationic pocket-like coordination polymer built by mixed double-hydrogen-bonded and coordinated 4,4′-bipyridine rectangular-grid with inclusion species, and this material has been fabricated into metal–organic nanofibers by electrospinning.
