Abstract
In the cation of the title salt, [Ag(C13H11N3)2]NO3, the Ag(I) atom lies on a crystallographic inversion center and is coordinated by four N atoms from two bidentate 2-(1H-benzimidazol-2-yl)aniline ligands in a distorted square-planar geometry. The Ag-N(aniline) bond [2.729 (2) Å] is significantly longer than the Ag-N(imidazole) bond [2.165 (1) Å]. In the ligand, the aniline ring is twisted by 37.87 (6)° from the mean plane of the benzimidazole ring system. The nitrate anion lies on a crystallographic twofold rotation axis which passes through the N atom and one of the O atoms. In the crystal, N-H⋯O hydrogen bonds link the components, forming a layer parallel to the bc plane.

Summary
Supporting information: this article has supporting information at journals.iucr.org/e. Azole and benzazole derivatives have been of interest in an important group in biological systems (Esparza-Ruiz et al., 2011; Hock et al, 2013). Benzimidazoles have shown antiviral and antitumor activity (Wang et al, 2007; Ramla et al, 2007). Some transition metal complexes with benzimidazole derivatives are important biological molecules (Sánchez-Guadarrama et al, 2009; Gökçe et al, 2005). The complexes of silver(I) with a series of benzimidazole-based N-heterocyclic carbenes have shown in vitro antibacterial potential against E. coli and B. subtilis bacteria (Haque et al, 2015). We reported on the synthesis and structural features of a zinc complex with a benzimidazole derivative (Kim & Kang, 2015). In a continuation of our research in this area, the title complex has been synthesized and characterized by single crystal diffraction
