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.
