Abstract

The vanadate NaMn4(VO4)3 was obtained as dark-brown 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)Mg(AsO4) 3 type, space group I4̄2d. The structure was refined from single-crystal diffractometer data: a = 7.0238(2), c = 19.8360(9) Å, R(F) = 0.013, wR(F) = 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.
