Abstract

In the binuclear title compound, [Ag2(C11H11N3)2](ClO4)2·2C2H6SO, the complex cation is centrosymmetric, with the unique AgI cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridine-2-ylmethyl)pyridine-3-amine ligands in a geometry slightly distorted from linear [N—Ag—N = 170.78 (9)°], resulting in the formation of a 16-membered cyclic dimer. The two pyridine rings coordinating to the AgI atom are almost perpendicular to each other [dihedral angle = 87.73 (10)°]. Intermolecular Ag⋯O interactions [3.149 (3) and 2.686 (3) Å], N—H⋯O and C—H⋯O hydrogen bonds and C—H⋯π interactions between the cyclic dimers and the anions or the solvent molecules lead to the formation of a three-dimensional supramolecular network.

Highlights

In the binuclear title compound, [Ag2(C11H11N3)2](ClO4)22C2H6SO, the complex cation is centrosymmetric, with the unique AgI cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridine-2-ylmethyl)pyridine-3amine ligands in a geometry slightly distorted from linear
Hydrogen bonds and C—H interactions between the cyclic dimers and the anions or the solvent molecules lead to the formation of a three-dimensional supramolecular network
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
