Bis[μ-2-(3-pyridylmethyl)-2H-benzotriazole]bis[nitratosilver(I)]

Abstract

In the title centrosymmetric binuclear AgI complex, [Ag2(NO3)2(C12H10N4)2], each AgI center is coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 2-(3-pyridylmethyl)-2H-benzotriazole (L) ligands, and an O atom of a coordinated NO3− anion in a distorted T-shaped geometry. This forms a unique box-like cyclic dimer with an intramolecular non-bonding Ag...Ag separation of 6.327 (2) Å. Weak intermolecular Ag...O(nitrate) interactions [2.728 (4) and 2.646 (3) Å] link the binuclear units, forming a two-dimensional network parallel to (100). Intermolecular C—H...O hydrogen-bonding interactions, involving the L ligands and the coordinated NO3− anions, link the sheets, forming a three-dimensional framework.
