Source of material

A 5 mL aqueous solution of AgNO3 (0.2 mmol) and KBrO3 (0.2 mmol) was added to a tube. Then 5 mL 1:1 CH3CN/H2O solution (v/v) was slowly added. Finally a 5 mL CH3OH solution of 1,2-bis(1,2,4-triazol-4-yl)ethane (btre) (0.1 mmol) was slowly added. Colorless crystals of the title compound (yield: 32% based on btre) were obtained after 1 weeks in a dark room at room temperature.

Experimental details

Carbon-bound hydrogen atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C).

Atomic coordinates of the hydrogen atoms of the water molecule were refined freely.

Discussion

The design of metal–organic coordination polymers are of current interest in the fields of supramolecular chemistry and crystal engineering not only because of their potential applications as functional materials but also due to their intriguing variety of topologies [3]. A successful strategy for construction of such networks is to employ appropriate ligands that can bond metal ions in different modes and provide a way to obtain new materials with intriguing architectures and excellent physical properties [4], [5], [6], [7]. Many factors such as the coordination geometry of the central atom, the structural characteristics of the ligands, the solvent system, and the counterions can play key roles in the construction of the coordination networks. The anions serve more than merely balancing the charges of a cationic complex and influence the structure of a supramolecular system through coordination to the metal. Silver coordination polymers have been widely studied not only for their applications as fluorescent materials, but also for their fascinating structures derived from variable coordination numbers from 2 to 6 of silver and different conformations around silver metal centers. Only a limited number of silver coordination polymers with the flexible 1-substituted 1,2,4-triazole ligands bis(1,2,4-triazol-1-yl)methane (btm) and 1,2-bis(1,2,4-triazol-1-yl)ethane (bte) [8], [9], [10] were synthesized and structurally characterized. The ligand 1,2-bis(1,2,4-triazol-4-yl)ethane is a isomer of 1,2-bis(1,2,4-triazol-1-yl)ethane (bte). Liang and coworkers reported that the self-assembly reaction of flexible ligand 1,2-bis(1,2,4-triazol-4-yl)ethane (btre) with Ag salt with BF4−, SO42−, NO3− and ClO4− gives novel coordination polymers with the anions playing an important role in the formation of coordination polymers [11]. On the other hand, a large number of mononuclear, oligonuclear, and polynuclear transition metal complexes of 1- and 4-substituted 1,2,4-triazole derivatives have been synthesized and characterized because of their unique properties and novel topologies. In order to continue to investigate the influence of the inorganic anions on the structures of silver coordination polymers with the flexible ligand btre, a new silver coordination polymer Ag(btre)BrO3⋅H2O was synthesized.

The asymmetric unit of the title structure consists of one Ag(I) ion, one 1,2-bis(1,2,4-triazol-4-yl)ethane, one bromate counter anion and one water molecule. Each Ag(I) atom displays a distorted tetrahedral coordination geometry, coordinated by four triazole nitrogen atoms from four symmetry-related btre ligands, and form a three-dimensional microporous structure, while BrO3− anions and water molecules occupy the voids (cf. the figure).

The Ag—N bond lengths are in the range of 2.192(4) Å to 2.540(5) Å. The N—Ag—N bond angles are in the range of 96.24(17)° to 145.29(17)°. The Br—O bond lengths are in the range of 1.627(5)–1.633(5) Å. There are weak interactions between two oxygen atoms of adjacent BrO3− anion and hydrogen atom of H2O [H(1w)–O(4) 0.90(2) Å, H(2w)–O(4) 0.88(2) Å]. Each Ag(btre)4 unit is a four-connected mode. If a Ag(btre)4 unit is considered as one node and double btre as one building block, the two-dimensional network can be viewed as a simple two-dimensional (4,4) network. The distances between the Ag(I) atoms bridged by btre are 3.9492(19) Å to 6.6050(41) Å, along the b-axis and along the a-axis. So each silver(I) chain connects four adjacent btre ligand bridges, leading to a novel three-dimensional network. Though microporous voids exist, the interpenetrating network does not occur, while BrO3− anions and water molecules occupy the voids.
