Crystal structure of bis[2-(1H-benzimidazol-2-yl)aniline]silver(I) nitrate
In the cation of the title salt, [Ag(C13H11N3)2]NO3, the AgI 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.
