Crystal structure and Hirshfeld surface analysis of 4,4'-(propane-1,3-diyl)bis(4H-1,2,4-triazol-1-ium) penta-fluorido-oxidovanadate(V)

Crystal structure of tetra-kis-(μ-4-benzyl-4H-1,2,4-triazole-κ2 N 1:N 2)tetra-fluoridodi-μ2-oxido-dioxidodisilver(I)divanadium(V)

The crystal structure of the title compound, [Ag2(VO2F2)2(C9H9N3)4], is presented. The mol-ecular complex is based on the heterobimetallic AgI-VV fragment {AgI 2(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 inter-actions is also described.
