(a) Fragment of the double hydrogen-bonded chain showing the cis-directing function of the [VOF5]2− anions (with respect to the strongest N—H⋯F hydrogen-bond donors) and short anion⋯π contact subtended by the triazole ring to the O1/F2/F5 face of the anion. (b) Structure of the hydrogen-bonded layer, viewed nearly down the c axis, with the strongest hydrogen bonds and two kinds of stacking interactions indicated by blue and red dotted lines, respectively.
