A Luminescent Rod-Packing Organic-Inorganic Hybrid Framework Based on Copper(I) Cyanide Ribbon and 5-(4-Pyridine)tetrazole Ligand

The hydrothermal reaction of CuCN, K3Fe(CN)(6) and 5-(4-pyridine)tetrazole generated a novel three-dimensional organic-inorganic hybrid framework, namely, {Cu-3(5PyTAZ)(CN)(2)} (n) (1) (5PyTAZ = 5-(4-pyridine)tetrazole). X-ray single-crystal diffraction shows that two independent Cu(I) centers are four-coordinate tetrahedral and three-coordinate trigonal geometries, which are connected by mu (3)-CN groups to form a 1D [Cu-3(CN)(2)] (n) inorganic ribbon along the c-axis direction. Each 5PyTAZ ligand links four adjacent inorganic ribbons via its five N-atoms to generate a complex 3D hybrid structure. If the 1D copper(I) cyanide ribbon was regarded as rod-shape building block, 1 exhibits a simple rod-packing topological framework. Furthermore, 1 is characterized by X-ray powder diffraction, elemental analysis, FT-IR, Raman spectra and TG/DTA. Notably, solid-state luminescence measurements indicate that 1 is a potential photoluminescence material.
