Synthesis and Characterization of Organically Templated Copper Halides with Zero and One-dimensional Hybrid Structures: (nbq)4Cu4I8 and [(ipq)2(Cu5I7)]n

Two new organically templated copper halides, (nbq)4Cu4I8 (1) and [(ipq)2(Cu5I7)]n (2) have been synthesized in the presence of nbq+ and ibq+ (nbq+ = N-(n-butyl)-quinolinium, ibq+ = N-(iso-pentyl)-quinolinium) acting as structure-directing agents(SDAs). Both of the compounds present hybrid structures with SDAs and inorganic moieties being incorporated. In 1, tetrameric Cu4I84− anion is composed by edge-sharing CuI4 tetrahedrons and CuI3 planar triangles. But the inorganic framework of 2 presents one-dimensional arrangement which results from the tetrahedron CuI4 and pseudo trigonal pyramid CuI3 through edge-sharing fashion. Electrostatic interactions between organic counter cations and inorganic moieties could be observed and contribute to the crystal packing. Both compounds are further characterized by IR, UV–Vis, elemental analysis, fluorescence and cyclic voltammetry.
