Chen, Jing; Shao, Chun-Fu; Bi, Yan; Yu, Wen-Jing published the article 《Hydrothermal Syntheses, Crystal Structures, and Fluorescent Properties of Zn(II) Coordination Complexes With 4-Amino-3,5-Bis(2-Pyridyl)-1,2,4-Triazole and Different Aromatic Dicarboxylic Acids》. Keywords: zinc aminopyridyltriazole aromatic dicarboxylate complex hydrothermal preparation crystal structure; luminescence zinc aminopyridyltriazole aromatic dicarboxylate complex.They researched the compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine( cas:1671-88-1 ).Quality Control of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1671-88-1) here.
Three new Zn(II) supramol. complexes {[Zn(2-bpt)(tp)(H2O)](H2O)}∞ (1), [Zn(2-bpt)2(Hpa)2] (2), and [Zn(2-bpt)2(H2O)2](Hip-NO2)2 (3) were synthesized under hydrothermal conditions by using 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole (2-bpt) and Zn(OAc)2 with the presence of different aromatic dicarboxylic acids (H2tp = terephthalic acid, H2pa = phthalic acid, and H2i.p.-NO2 = 5-nitroisophthalic acid). Complex 1 shows a one-dimensional zigzag chain array, 2 represents a neutral mononuclear mol., and 3 consists of the cationic mononuclear coordination unit and Hip-NO2 anion. Notably, in complex 3, the H2i.p.-NO2 ligand is partly deprotonated to balance the charge and uncoordinated to the metal center. In all three structures, the low-dimensional coordination motifs are further extended to distinct two-dimensional or three-dimensional supramol. networks via H-bonding and/or π···π stacking interactions. Fluorescent properties for 1-3 also were studied in solid state at room temperature
