SDS of cas: 14389-12-9. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-(4-Pyridyl)-1H-tetrazole, is researched, Molecular C6H5N5, CAS is 14389-12-9, about New Cu(II) and Cd(II) coordination polymers employing 5-[N-acetato(4-pyridyl)]tetrazolate as a bridging ligand. Author is Yang, Gao-Wen; Li, Qiao-Yun; Wang, Jun; Yuan, Rong-Xin; Xie, Ji-Min.
Two coordination polymers [Cu(a4-ptz)2·2H2O]n, (1) and [{Cd(a4-ptz)·(H2O)2Cl}·H2O]n (2) (a4-ptz = 5-[N-acetato(4-pyridyl)]tetrazolate) were synthesized and characterized by elemental anal., IR spectroscopy, thermal anal., and X-ray crystal structure anal. Complex 1 exhibits a 2D square grid polymeric structure with dimensions of 1.220 0 nm × 1.220 0 nm. Complex 2 possesses a 1D Z-type polymeric chain, which contains four-membered ring (Cd2Cl2). The thermal stability of complex 2 up to about 280°C (TGA measurement) and their insolubility in common solvents make it a good candidate for potential fluorescent materials.
