A cationic copper-iodine cluster-based metal-organic framework (MOF) with (4, 8)-connected fluorite topology

A new copper-iodine based metal-organic framework compound, [Cu3(L)I2·H2O]n (1) (L = 5-(4-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 Cu6I4 cationic clusters, which has a (4, 8)-connected fluorite (flu) topological network. Photoluminescent (PL) investigation reveals that compound 1 displays strong yellow-light emission.
