Pressure-induced isostructural phase transition of a metal-organic framework Co2(4,4′-bpy)3(NO3)4·xH2O

摘要

Based on the 4,4′-bipyridine organic linker, metal-organic frameworks of Co2(4,4′-bpy)3(NO3)4·xH2O (CB-MOF) have been prepared. The pressure-dependent structure evolution of CB-MOF has been investigated up to 11 GPa. An isostructural phase transition was observed at about 6 GPa followed by negative compressibility along the b axis.
