title: Structural Diversity and Properties of M(II) Coordination Compounds Constructed by 3-Hydrazino-4-amino-1,2,4-triazole Dihydrochloride as Starting Material.
abstract: Twelve metal coordination compounds with two triazole derivatives, namely, {[Mn(HATr)2](ClO4)2}n (1), [Mn(HATr)3]Cl(ClO4) (2), [Co3(ATr)6(H2O)6](ClO4)6·4.5H2O (3), [Co(HATr)3]Cl(ClO4) (4), [Co2Cl2(HATr)2(H2O)2(CH3OH)2]Cl2·2H2O (5), [Ni3(ATr)6(H2O)6](ClO4)6·4.5H2O (6), [Ni(HATr)3]Cl(ClO4) (7), [Ni2Cl2(HATr)2(H2O)4](ClO4)2·4H2O (8), [Ni2(HATr)2(H2O)6](ClO4)4·2H2O (9), {[Zn(HATr)2](ClO4)2}n (10), [Zn(HATr)3]Cl(ClO4) (11), and {[Cd4(HATr)8](CdCl4)Cl2(ClO4)4}n (12), when HATr = 3-hydrazino-4-amino-1,2,4-triazole and ATr = 4-amino-1,2,4-triazole, were prepared under diverse conditions and structurally characterized. Compounds 1, 10 and 12 exhibit one-dimensional zigzag chain structures; 2, 4, 7, and 11 possess mononuclear structures; 3 and 6 display trinuclear structures, while 5, 8, and 9 feature binuclear structures. Hydrogen bonds link these compounds into three-dimensional structures. The thermal stability and energetic properties also were determined.
