Crystal structure of catena-poly[[(N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide-κN1)silver(I)]-μ-nitrato-κ3O,O′:O]

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 molecule, one AgI atom and one nitrate ion. The AgI atom, with a distorted trigonal–pyramidal environment, is coordinated by one nitrogen 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 interactions, resulting in a three-dimensional architecture.
