Safety of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about The synthesis and characterisation of Rh(III) complexes with pyridyltriazole ligands.
Rh(III) mixed ligand polypyridine type complexes were prepared [Rh(L)2(L’)]n+, where n = 2/3, L = 2,2′-bipyridine (bpy)/1,10-phenanthroline (phen) and L’ = 3-(pyridin-2-yl)-1,2,4-triazole (Hpytr), 1-methyl-3-(pyridin-2-yl)-1,2,4-triazole (1M3pytr), 4-methyl-3-(pyridin-2-yl)-1,2,4-triazole (4Mpytr), 3,5-bis(pyridin-2-yl)-1,2,4-triazole (Hbpt), 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole (NH2bpt) and 3-(pyridin-2-yl)-5-phenyl-1,2,4-triazole (HPhpytr), were prepared and their synthesis and characterization are reported. Crystals of [Rh(bpy)2(Phpytr)](PF6)2 and [Rh(phen)2(NHbpt)](PF6)2 were obtained and their structures determined Anal. of x-ray crystallog. data showed that coordination of the metal center in [Rh(phen)2(NHbpt)](PF6)2 occurs via the amine moiety and a N of the pyridine ring. NMR studies illustrated that coordination to the NH2bpt ligand was also possible via a N of the triazole ring and the pyridine ring forming [Rh(phen)2(NH2bpt)](PF6)3. The absorption and emission properties of the complexes studied are π-π* in nature and preliminary evidence suggests that all complexes with the exception of [Rh(phen)2(NHbpt)](PF6)2 and [Rh(bpy)2(NHbpt)](PF6)2 are dual emitting at 77 K.
