摘要

A new two-dimensional Cu(I)-framework [Cu₃(deppz)(mtta)I] (1) [(Hdeppz = 3,5-diethyl-4-(4-pyridyl)-pyrazole, Hmtta = 5-methyltetrazole] has been solvothermally synthesized and structurally characterized. The framework contains an unprecedented cyclic Cu₄(渭-pz)₂(渭-mtta)₂ cluster (Cu₄) with twelve-membered coplanar Cu₄N₈ metallocycle, which contains coordinatively unsaturated Cu(I) centers and acts as a soft 蟺-acid motif to contact with iodine atoms from Cu₂I₂ dimer of adjacent layers, generating a 3D supramolecular framework. The framework exhibits high thermostability and bright green-blue solid-state luminescence.
