Dalton Trans. 2015, 44, 20441-20448. doi: 10.1039/c5dt03445k.1477-922610.1039/c5dt03445khttps://hdl.handle.net/20.500.14352/92970Two new cation-ordered polymorphs of Mn2ScSbO6 have been synthesised at high-pressure. At 5.5 GPa and 1523 K Mn2ScSbO6 crystallizes in the Ni3TeO6-type structure with the polar R3 space group and cell parameters a = 5.3419 (5) Å and c = 14.0603 (2) Å. Below TC = 42.0 K it exhibits ferrimagnetic order with a net magnetization of 0.6μB arising from unusual site-selective Mn/Sc disorder and is thus a potential multiferroic material. A double perovskite phase obtained at 12 GPa and 1473 K crystallizes in the nonpolar P21/n monoclinic space group with cell parameters a = 5.2909 (3) Å, b = 5.4698 (3) Å, c = 7.7349 (5) Å and β = 90.165 (6) °. Magnetization and neutron diffraction experiments reveal antiferromagnetic order below TN = 22.3 K with the spins lying in the ac plane.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1039/c5dt03445kopen access546High pressureMultiferroicNeutron diffractionMagnetic propertiesCrystallographyQuímica inorgánica (Química)Materiales2303.29 Elementos de Transición2303.26 Estructura de Los Compuestos Inorgánicos2211.17 Propiedades Magnéticas2211.04 Cristalografía2213.03 Altas Presiones
