title: Crystal structure of aqua-bis-[2-(1H-benzimidazol-2-yl-κN (3))aniline-κN]zinc dinitrate.
abstract: The cation of the complex title salt, [Zn(C13H11N3)2(H2O)](NO3)2, lies about a twofold rotation axis, which passes through the Zn(II) atom and the O atom of the aqua ligand. The Zn(II) atom adopts a distorted trigonal-bipyramidal geometry defined by two N atoms in axial positions [angle = 166.24 (7)°], and two N and one O atom in the equatorial plane [range of angles: 115.17 (7)-122.42 (3)°]. The dihedral angle between the imidazole and aniline rings is 23.86 (5)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the components into a three-dimensional network.
