The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《A Luminescent Rod-Packing Organic-Inorganic Hybrid Framework Based on Copper(I) Cyanide Ribbon and 5-(4-Pyridine)tetrazole Ligand》. Authors are Zhai, Quan-Guo; Chen, Shuang-Qiu; Li, Shu-Ni; Jiang, Yu-Cheng; Hu, Man-Cheng.The article about the compound:5-(4-Pyridyl)-1H-tetrazolecas:14389-12-9,SMILESS:C1(C2=NN=NN2)=CC=NC=C1).Safety of 5-(4-Pyridyl)-1H-tetrazole. Through the article, more information about this compound (cas:14389-12-9) is conveyed.
The hydrothermal reaction of CuCN, K3Fe(CN)6 and 5-(4-pyridine)tetrazole generated a novel three-dimensional organic-inorganic hybrid framework, namely, {Cu3(5PyTAZ)(CN)2}n (1) (5PyTAZ = 5-(4-pyridyl)tetrazolate). 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 μ3-CN groups to form a 1-dimensional [Cu3(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 3-dimensional hybrid structure. If the 1-dimensional Cu(I) cyanide ribbon was regarded as a rod-shape building block, 1 exhibits a simple rod-packing topol. framework. Also, 1 was characterized by x-ray powder diffraction, elemental anal., FTIR, Raman spectra and TG/DTA. Notably, solid-state luminescence measurements indicate that 1 is a potential photoluminescence material.
