COA of Formula: C6H5N5. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5-(4-Pyridyl)-1H-tetrazole, is researched, Molecular C6H5N5, CAS is 14389-12-9, about Presynthesized and In-Situ Generated Tetrazolate Ligand in the Design of Chiral Cadmium Coordination Polymer. Author is Chang, Che-Chi; Huang, Yun-Chieh; Huang, Sheng-Ming; Wu, Jing-Yun; Liu, Yen-Hsiang; Lu, Kuang-Lieh.
In contrast to the in-situ generated 5-(4-pyridyl)tetrazolate (4-ptz) ligand, the use of presynthesized 4-ptz gave a chiral cadmium coordination polymer [Cd2Cl3(4-ptz)]n (1) with a rare μ5-bridging mode of the tetrazolate ligand. Reaction of the ligand generated in-situ from 4-cyanopyridine and NaN3 yielded an achiral complex [Cd2Cl2(OH)(4-ptz)(H2O)]n (2). Crystal structures for both complexes 1 and 2 were determined This type of tuning in the design of chiral coordination polymers is reported for the first time.
