The material structure described by NaMn3Ag(PO4)3 crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(4) and four equivalent O(3) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms to form distorted MnO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Mn(2)O6 octahedra.

Ag(1) is bonded in a distorted square co-planar geometry to four equivalent O(6) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with four equivalent Mn(2)O6 octahedra.
