V₂O₂F₄(H₂O)₂·H₂O: a new V⁴⁺ layer structure related to VOF₃

Research output: Contribution to journal › Article › peer-review

Abstract

The title compound, V₂O₂F₄(H₂O)₂·H₂O, (I), features a new infinite, V⁴⁺-containing, two-dimensional layer, comprised of fluorine bridged corner-sharing and edge-sharing VOF₄(H₂O) octahedral building units. Synthesis was carried out under solvothermal conditions. The V⁴⁺ centre exhibits a typical off-centring, with a short V=O bond and elongated trans V—F bond. Hydrogen bonded water molecules occur between the layers. The structure is related to previously reported vana- dium oxyfluoride structures, in particular the same layer topology is seen in VOF₃.
