resumo
A novel 3-D cuprous iodide polymer [(Cu3I)-I-I(mu(6)-L)](n) with a Cu/I ratio as high as 3 (1, H2L = 1,3-bis(2H-tetrazol-5-yl)benzene) has been hydrothermally synthesized. The 3-D framework of 1 is constructed by the linkages of rare 1-D cationic aggregates [(Cu3I2+)-I-I](n) and anionic bi-tetrazolate bridges. 1 shows unusually thermo-chromic luminescent and photocatalytic properties, and its density functional theory calculation has also been studied.
