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

The crystal structure of the title compound, [Ag 2 (VO 2 F 2 ) 2 (C 9 H 9 N 3 ) 4 ], is presented. The mol-ecular complex is based on the heterobimetallic Ag I -V V fragment {Ag I 2 (V V O 2 F 2 ) 2 ( tr ) 4 } supported by four 1,2,4-triazole ligands [4-benzyl-(4 H -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 [VO 2 F 2 N] 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.
