Abstract

Manganese orthovanadate Mn3(VO4)2 single crystals were grown for the first time from a flux of MnO/V2O5/MoO3. The flux and oxygen partial pressure used are the key factors for the crystal growth and prevention of the oxidation of Mn2+ and the reduction of V5+ during the crystallization process. The reduction and oxidation chemistry of Mn3(VO4)2 was studied. Mn3(VO4)2 is isostructural with magnesium orthovanadate Mg3(VO4)2, orthorhombic, space group Cmca, a = 6.247(1) Å, b = 11.728(2) Å, c = 8.491(2) Å and Z = 4, as determined by single crystal X-ray diffraction. Because it is a Mn2+ deficient spinel structure there are two-dimensional sheets of Mn2+O6 octahedra within the structure which show unusual ferrimagnetic properties.
