Hydrothermal crystal growth, structures and thermal properties of Co(II)-4,4′-bipyridine-based coordination polymeric materials

Hydrothermal synthetic parameters were studied and optimized for the preparation of new coordination polymeric materials based on Co(II) and 4,4′-bipy. A new polymeric compound, [Co2(H2O) 2(OH)2(4,4′-bipy)8](NO3) 2·2(4,4′-bipy) 10(H2O) (1), was prepared and structurally characterized by single cryst...
