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 A new cobalt(II) complex with 5-(4-pyridyl)tetrazole ligands. Author is Zhu, Wei Feng; Zhou, Xing Fen.
A new mononuclear Co(II) complex, tetraaquabis[5-(4-pyridyl)tetrazolido-κN5]cobalt(II) dihydrate, [Co(C6H4N5)2(H2O)4].2H2O, was synthesized and structurally characterized. The Co(II) atom is coordinated by 2 N atoms from 5-(4-pyridyl)tetrazole ligands, as well as 4 O atoms from coordinated H2O mols. The mol. is centrosym., with pairs of equivalent ligands lying trans to each other in a slightly distorted octahedral coordination geometry. A prominent feature of the complex is the formation of a 3D supramol. network via O-H…O and O-H…N H-bonds. Crystal data: triclinic, space group P1̅, a = 7.2087(16), b = 7.8002(17), c = 8.6702(18) Å, α = 91.406(3), β = 90.482(3), γ = 100.953(3)°, Z = 1, R = 0.031, Rw = 0.083 for 1562 observed reflections with I > 2σ(I) and 157 refined parameters. The at. coordinates and bonding distances are given.
