An unprecedented [Cu7I4]3 + cationic cluster-based metal–organic framework (MOF) including 1D nanochannels

A new cationic copper–iodine based metal–organic framework compound, [Cu7I4L3(H2O)]n (1) (L = 5-(3-pyridyl)tetrazole), has been synthesized by solvothermal method. X-ray analysis shows that compound 1 is a 3-D metal–organic framework constructed by the L ligands linking new discrete (Cu7I4)3 + cationic clusters, which has an uncommon (3, 9)-connected gfy topological network including 1D hexagonal nano-channels.
