NaVMnO4 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form distorted NaO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and corners with four equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 76-80°. V(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form VO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and corners with four equivalent Na(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 43-55°. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Na(1)O4 tetrahedra, corners with six equivalent V(1)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Na(1), one V(1), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Na(1), one V(1), and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Na(1), one V(1), and one Mn(1) atom.
