The vanadate NaMn4(VO4)3 was obtained as darkbrown crystals as a side-product during the crystallization of the oxygen-deficient perovskite Na3MnV2O7.5 in an NaCl/KCl flux. NaMn4(VO4)3 crystallizes with the tetragonal (Mg1/21/2)Mg4(AsO4)3 type, space group I42¯ d. The structure was refined from single-crystal diffractometer data: a = 7.0238(2), c = 19.8360(9) A, ˚ R(F) = 0.013, wR(F2) = 0.033, 853 F2 values, and 49 variables. The NaMn4(VO4)3 structure is built up of different sheets stacked perpendicular to the c axis. Na, Mn and V atoms are located in dodecahedra, octahedra and tetrahedra, respectively< Réduire
