In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis, crystal structure and magnetic properties of [Cu(mal)(abpt)(H2O)]·3/2H2O and [Cu2(sq)(abpt)2]·2H2O (mal = malonate, sq = squarate, abpt = 4-amino-3,5-di-2-pyridyl-4H-1,2,4 triazole), published in 2011, which mentions a compound: 1671-88-1, Name is 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, Molecular C12H10N6, Application In Synthesis of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.
Two new mixed-ligand complexes of formula [Cu(mal)(abpt)(H2O)]·3/2H2O (1) and [Cu2(sq)(abpt)2]·2H2O (2) [mal = malonate, abpt = 4-amino-3,5-di-2-pyridyl-4H-1,2,4-triazole and sq = squarate], were prepared and characterized by x-ray crystal structure determination and magnetic studies. Complex 1 crystallizes in the monoclinic system, space group C2/c, with a 14.0086(2), b 10.0980(2), c 25.630(4) Å; β 97.5900(10)°, and Z = 8. Complex 2 crystallizes in the triclinic system, space group P1̅ with a 7.5696(15), b 8.4697(17), c 11.049(2) Å; β 93.00(3)°, α 96.98(3), γ 90.111(3)°and Z = 1. Complex 1 consist of a neutral mononuclear [Cu(mal)(abpt)(H2O)] unit and water mol. of crystallization in a distorted square pyramidal coordination sphere, while complex 2 is viewed as being made up of [Cu(sq)(abpt)2] units with the squarato ligand bridging the two copper(II) cations. Variable temperature magnetic behavior of the complexes reveals the existence of weak antiferromagnetic interaction for complex 1 and weak ferromagnetic intrachain interaction for complex 2.
Different reactions of this compound(3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine)Application In Synthesis of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine require different conditions, so the reaction conditions are very important.
