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, structural characterization, molecular docking, and urease inhibition studies of dinuclear cobalt(II) complexes derived from 3,5-bis(pyridin-2-yl)-4-amino-1,2,4-triazole, published in 2014, which mentions a compound: 1671-88-1, Name is 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, Molecular C12H10N6, Recommanded Product: 1671-88-1.

Two dinuclear Co(II) complexes, [Co2(L)2(EtOH)4]·4ClO4 and [Co2(L)2(H2O)2(NO3)2]·2NO3 (= 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole), were obtained and characterized by IR, elemental anal., and single-crystal x-ray diffraction anal. The stabilization of their crystal lattices is maintained by strong H-bonds between counterions and host framework, which lead to various supramol. architectures. The urease inhibitory properties were studied, where the two complexes revealed strong urease inhibition activities. Docking simulations of were performed with H. pylori urease (PDB code: 1E9Z) to rationalize their binding models.

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.

Five new complexes were obtained from solution or hydrothermal reactions of M(OAc)2 (M = Mn, Cu and Cd) or CuCl2 with 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole (abpt) and NaN3 or 1,3,5-benzenetricarboxylic acid (btcH3) in different molar ratios. Structural anal. reveals that Cd(abpt) units in [Cd(abpt)(μ1,1-N3)2]n (1) are bridged by double μ1,1 end-on (EO) azides into 1-dimensional zigzag coordination chains. Similar structural motifs, i.e. the chelation of abpt to the metal center and the double bridges of EO azides, are found in [Mn4(abpt)4(μ1,1-N3)8(H2O)2] (2). The terminal aqua mols. and the monodentate N3- groups give a tetranuclear complex rather than a polymeric compound The abpt underwent deamination in the presence of copper ions during the process of coordination and became 3,5-bis(pyridin-2-yl)-1,2,4-triazolate (bpt-H) in 3-5. [Cu4(bpt-H)4(N3)4]·4.5H2O (3) is a neutral tetranuclear grid-like complex, in which the azides act as monodentate ligands. A similar [Cu4(bpt-H)4]4+ grid-like unit was found in [Cu4(bpt-H)4(μ-btcH)Cl2]·2H2O (4) and a pair of symmetry-related copper atoms are bridged by the μ-btcH2- coligand in a butterfly-shaped structure. In [Cu2(bpt-H)(μ6-btc)(H2O)]n (5), the tetranuclear {Cu4(μ-bpt-H)2(μ3-carboxylate)2}4+ units are bridged by μ6-btc3- ligands in a 2-dimensional step-like layer structure. Temperature-dependent magnetic susceptibility measurements reveal that the double μ1,1-N3- bridges in 2 transmit the ferromagnetic interactions between Mn2+ centers (J1 = J2 = +3.09(4) cm-1, gMn(ii) = 2.02(1)), and the μ-(bpt-H)- bridges transmit moderate antiferromagnetic interactions in both 3 (J = -12.78(13) cm-1) and 4 (J1 = -14.96(11) cm-1). In 4 the antiferromagnetic coupling via the μ-btcH2- bridge is the 2nd coupling pathway (J2 = -9.48(7) cm-1). The coexistence of ferromagnetic and antiferromagnetic coupling between four Cu2+ centers occurs in 5 (J1 = -0.88(3) cm-1 and J2 = +5.01(2) cm-1). The magneto-structural relation for tetranuclear copper pyrazolate/triazolate compounds is discussed.
