Abstract
The phase relationships in the pseudobinary MgMoO4-Mg3V2O8 system have been determined by differential thermal analysis and X-ray diffraction analysis. The intermediate compound Mg2.5VMoO8 was found to exhibit a considerable solid solution Mg2.5+xV1+2xMo1-2xO8 (-0.05 ≤ * ≤ 0.05) at 1100 °C in air. Single crystals with composition of Mg2.54V1.08Mo0.92O8 were successfully grown from the Mg-V-Mo-Oxide flux. Mg2.54V1.08Mo0.92O8 crystallizes in the orthorhombic system, space group Pnma with a = 5.058(1) Å, b = 10.307(3) Å, c = 17.402(4) Å, Z = 6. The vanadium and molybdenum cations remain in their highest oxidation states and charge neutrality associated with the variation of the V/Mo atomic ratio is balanced by an increase or decrease in the number of magnesium cations in the crystal.
