Vanadium(III) fluoride is the chemical compound with the formula V F₃. This yellow-green, refractory solid is obtained in a two-step procedure from V₂O₃. Similar to other transition-metal fluorides (such as MnF₂), it exhibits magnetic ordering at low temperatures (e.g. V₂F₆.4H₂O orders below 12 K).
