Synthesis and characterization of a novel 3D copper(I) coordination polymer with a ligand generated in situ

Hydrothermal reaction of CuCl2 · 2H2O, NaN3 with 1,4-dicyanobenzene in water/ethanol yielded a novel Cu(I)-tetrazolate, {Cu(cptz)}n, (1) (Hcptz is 5-(4-cyanophenyl)-tetrazole). The cptz ligand in the complex was generated in situ through the [2 + 3] cycloaddition reaction involving one of the two cyano-groups of the precursor 1,4-dicyanobenzene. The structure characterization shows that 1 possesses a 3D 4-connected SrAl2 topological network. Additionally, complex 1 exhibits strong yellow fluorescence at room temperature in the solid state.
