Abstract
The reaction of silver nitrate and cafenstrole (N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide), a triazole herbicide, leads to the title coordination polymer, [Ag(NO3)(C16H22N4O3S)] n , whose asymmetric unit comprises one cafenstrole ligand mol-ecule, one AgI atom and one nitrate ion. The AgI atom, with a distorted trigonal-pyramidal environment, is coordinated by one nitro-gen atom of a triazole ring, two oxygen atoms of a nitrate ion and one oxygen atom of a neighboring nitrate ion. The coordination bonds between silver and oxygen atoms give rise to a one-dimensional (1D) coordination polymer structure along [001]. The dihedral angle between the planes of the triazole and benzene rings is 87.13 (11)°. In the crystal, the coordination polymer is stabilized by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, resulting in a three-dimensional architecture.

It is very likely that triazole–metal interactions play a major role in the biological actions of triazole-containing drugs and agricultural chemicals
Summary
We have reported the crystal structure of the ligand cafenstrole (L; Kang et al, 2015). It is very likely that triazole–metal interactions play a major role in the biological actions of triazole-containing drugs and agricultural chemicals. 1,2,4-Triazole and its derivatives have gained great attention as ligands to transition metals (Haasnoot, 2000). To understand the interactions of triazoles with metals, further research on the structures of triazole–metal compounds is of great necessity. Our attention will be focused on the diversity of the coordination geometries of 1,2,4-triazole complexes with transition metal ions. We report the reaction of silver nitrate and cafenstrole to produce the title compound, which is a 1D silver(I) coordination polymer
