ABSTRACT

L–ag–l–ag–l–: The reaction of silver(I) nitrate with the mono-substituted pyrazine carboxamide ligand, N-(pyridin-2-ylmeth­yl)pyrazine-2-carboxamide (), led to the formation of the title compound with a metal–organic framework (MOF) structure, [Ag(C11H10N4O)(NO3)]n, poly[μ-nitrato-[μ-N-(pyridin-2-ylmethyl-κN)pyrazine-2-carboxamide-κN4]silver(I)]. The silver(I) atom is coordinated by a pyrazine N atom, a pyridine N atom, and two O atoms of two symmetry-related nitrate anions. It has a fourfold N2O2 coordination sphere, which can be described as distorted trigonal–pyramidal. The ligands are bridged by the silver atoms forming zigzag chains along the a-axis direction. The chains are arranged in pairs related by a twofold screw axis. They are linked via the nitrate anions, which bridge the silver(I) atoms in a μ2 fashion, forming the MOF structure. Within the framework there are N—H⋯O and C—H⋯O hydrogen bonds present.

Mentions: In the crystal of (I), the chains are bridged by the nitrate anions, leading to the formation of the three-dimensional framework structure (Figs. 3 ▸ and 4 ▸). The nitrate anions bridge the silver atoms in a μ2 manner (Fig. 4 ▸), one of the many ways in which the nitrate anion inter­acts with silver atoms (Cambridge Structural Database; Groom et al., 2016 ▸). Its role here is essential in forming the MOF structure.
