catena-Poly[[[tetraaquazinc(II)]-mu-4-amino-3,5-di-3-pyridyl-4H-1,2,4-triazole] sulfate monohydrate] and poly[[bis(mu-4-amino-3,5-di-4-pyridyl-4H-1,2,4-triazole)diaquacopper(II)] dinitrate octahydrate].
The isomeric bent triazole-containing ligands 4-amino-3,5-di-3-pyridyl-4H-1,2,4-triazole (L1) and 4-amino-3,5-di-4-pyridyl-4H-1,2,4-triazole (L2) have been used to create the two novel title complexes catena-poly[[[tetraaquazinc(II)]-mu-4-amino-3,5-di-3-pyridyl-4H-1,2,4-triazole] sulfate monohydrate], {[Zn(C(12)H(10)N(6))(H(2)O)(4)]SO(4).H(2)O}(n), (I), and poly[[diaquabis(mu-4-amino-3,5-di-4-pyridyl-4H-1,2,4-triazole)copper(II)] dinitrate octahydrate], {[Cu(C(12)H(10)N(6))(2)(H(2)O)(2)](NO(3))(2).8H(2)O}(n), (II). The Zn(II) and Cu(II) atoms are all six-coordinated in approximately octahedral environments. Compound (I) presents a sinusoidal chain generated by ZnO(4) cores which are bridged by L1 ligands in a cisoid conformation. These sinusoidal chains are bound to each other by O-H...O hydrogen bonds between coordinated water molecules of neighboring chains into a two-dimensional network. These layers stack in an ...ABAB... sequence and are further linked into a three-dimensional framework through O-H...N hydrogen bonds between coordinated water molecules and the N atoms of the triazole rings. In (II), the Cu(II) centers are bridged by the L2 ligands to form a two-dimensional network with square grids. All of the two-dimensional nets also stack alternately along the crystallographic a axis. Neighboring layers are further linked into a three-dimensional framework via interlayer N-H...N hydrogen bonds between -NH(2) groups of the triazole rings and the N atoms in the triazole rings.
