Two Cu4I4 coordination polymers, [Cu 2I2(aadtz)]n (1) and [Cu2I(dtz)] n (2) [aadtz = 4-[(1-aminoethylidene)-amino]-3,5-diethyl-1,2,4- triazole, dtz = 3,5-diethyl-1,2,4-triazole], were synthesized in a one-pot reaction of CuI and 4-amino-3,5-diethyl-1,2,4-triazole under solvothermal conditions. The organic components were generated in situ from a common triazolate source. The structures of the Cu4I4 units in the polymers are different. The Cu4I4 cluster in complex 1 is an inorganic 8-membered ring with a chair-chair conformation, while the one in complex 2 is a distorted cubane. The topologies of the complexes were assigned as a two-dimensional 4-connected grid for 1 and a three-dimensional (3,4)-connected jph-type framework for 2. In addition, the luminescent properties of the complexes in the solid state were also investigated. © 2009 The Royal Society of Chemistry.
