A new zinc coordination polymer, [Zn(atda)(4,4'-bipy)]n (H2atda = (4-amino-1,2,4-triazole-3,5-diyldithio)diacetic acid, 4,4'-bipy = 4,4'-bipyridine), was synthesized by rheological phase reaction method and characterized by elemental analysis, IR, UV and single-crystal X-ray diffraction. The results reveal that it possesses three-dimensional (3D) solid-state structure. The Zn(II) inos are interlinked by bridging of atda2 ligands and 1D [Zn(atda)]n double chains are constructed, which are further connected together by the coordination of 4,4'-bipy molecules and 2D double layered structure are generated. Hydrogen-bonding interaction exists between the layers, resulting in the formation of 3D supramolecular structure. In addition, thermal stability and fluorescent property were studied.

Two new complexes [Ni(phen)(H2O)4] (atda)(H2O)5 (1) and [Ni2(4,4' -bipy)2(H2O)8] (atda)2 (2) (where H2atda = (4-amino-1,2,4-triazole-3,5-diyldithio)diacetic acid, phen = 1,10-phenanthroline, 4,4' -bipy = 4,4' -bipyridine) have been synthesized and characterized by elemental analysis, IR, UV, thermogravimetric analysis and X-ray diffraction technique. X-ray structural analyses reveal that the two complexes are both three-dimensional (3D) supramolecular structures and possess similar structural characters. The Ni(II) centers are both in distorted octahedral coordination environments, six-coordinated by four water molecules and two nitrogen atoms from a 1,10-phenanthroline molecule or two 4,4' -bipyridine molecules. The atda2 - ligands do not coordinate to the Ni(II) centers, but only exist as counter anions, forming hydrogen bonds with coordinated or uncoordinated water molecules. Various hydrogen-bonding interactions play an important role in the assembly of three-dimensional supramolecular architectures.

Two new complexes, [Zn(phen)(H2O)(4)]center dot(atda)center dot(H2O)(5) (1) and [Zn(4,4'-bipy)(2)(H2O)(4)]center dot(atda) (2) (H(2)atda = (4-amino-1,2,4-triazole-3,5-diyldithio)diacetic acid, phen = 1,10-phenanthroline, 4,4'-bipy = 4,4'-bipyridine), have been synthesized and characterized. X-ray analyses revealed that in two complexes, the atda(2-) ligands act only as counteranions and three-dimensional (3D) supramolecular architectures are constructed via series of hydrogen-bonding interactions. Though the Zn(II) centers are both coordinated by four water molecules and two N atoms, the different arrangement style of coordinated water molecules in two complexes and the occurrence of lattice water molecules in complex 1 lead to different 3D structures. The IR and thermal analyses further confirmed the structural results.
