Bis[-1-(2-pyridylmethyl)-1H-benzotriazole]disilver(I) bis(perchlorate)

C.-S. Liu, X.-G. Xiao and M. Hu

Abstract: In the title centrosymmetric binuclear Ag^Icomplex, [Ag₂(C₁₂H₁₀N₄)₂](ClO₄)₂, each Ag^I center is two-coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 1-(2-pyridylmethyl)-1H-benzotriazole (L) ligands. This forms a unique box-like cyclic dimer with an intramolecular AgAg separation of 4.479 (2) Å. Intermolecular C-HO hydrogen-bonding interactions, involving uncoordinated ClO₄^- ions, link the binuclear units, forming a two-dimensional network parallel to (10 $\\overline{2}$ ).
