The double-perovskite Mn2VSbO6 has been synthesized by solid-state reaction under pressure at 6 GPa and temperature of 1200°C, and its crystal structure has been refined by X-ray powder diffraction date. Mn2VSbO6 crystallizes in monoclinic space group P121/n1 with the following parameters: a = 5.2340 Å (2), b = 5.3932 Å (2), c = 7.6460 Å (3), β = 89.6075° (23), V = 215.826 Å3 (14), Z = 2. It found that V and Sb atoms are completely ordered in 2d and 2c positions of double-perovskite structure, respectively. According to XPS measurements, manganese in this compound is present as Mn2+, while vanadium is V3+. The magnetization date suggests that Mn2VSbO6 transforms to an antiferromagnetic state due to simultaneous ordering of V3+ and Mn2+ magnetic sublattices at low temperature.
