Crystal structure of tetrakis(μ-4-benzyl-4H-1,2,4-triazole-κ2N1:N2)tetrafluoridodi-μ2-oxido-dioxidodisilver(I)divanadium(V)

Abstract

The crystal structure of the title compound, [Ag2(VO2F2)2(C9H9N3)4], is presented. The molecular complex is based on the heterobimetallic AgI—VV fragment {AgI2(VVO2F2)2(tr)4} supported by four 1,2,4-triazole ligands [4-benzyl-(4H-1,2,4-triazol-4-yl)]. The triazole functional group demonstrates homo- and heterometallic connectivity (Ag—Ag and Ag—V) of the metal centers through the [–NN–] double and single bridges, respectively. The vanadium atom possesses a distorted trigonal–bipyramidal coordination environment [VO2F2N] with the Reedijk structural parameter τ = 0.59. In the crystal, C—H...O and C—H...F hydrogen bonds as well as C—H...π contacts are observed involving the organic ligands and the vanadium oxofluoride anions. A Hirshfeld surface analysis of the hydrogen-bonding interactions is also described.
