Vanadium(III) oxide
Template:Chembox Vanadium(III) oxide is the inorganic compound with the formula V2O3. It is a black solid prepared by reduction of V2O5 with hydrogen or carbon monoxide.[1][2] It is a basic oxide dissolving in acids to give solutions of vanadium (III) complexes.[2] V2O3 has the corundum structure.[2] It is antiferromagnetic with a critical temperature of 160 K, below which there is an abrupt change in conductivity from metallic to insulating.[3] This also distorts the crystal structure to a monoclinic space group: C2/c.[4]
Upon exposure to air it gradually converts into indigo-blue V2O4.[3]
In nature it occurs as the rare mineral karelianite.[5]
