The structure described by MnFe2Ag2(PO4)3 crystallizes in the monoclinic C2/c space group. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MnO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with two equivalent Ag(2)O6 octahedra. Fe(1) is bonded to one O(1), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form FeO6 octahedra that share  a cornercorner with one Ag(2)O6 octahedra, corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra,  an edgeedge with one Mn(1)O6 octahedra, and  an edgeedge with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted square co-planar geometry to four equivalent O(4) atoms. In the second Ag site, Ag(2) is bonded to two equivalent O(6) and four equivalent O(2) atoms to form distorted AgO6 octahedra that share corners with two equivalent Fe(1)O6 octahedra, corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with two equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with two equivalent Ag(2)O6 octahedra, and corners with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-62°. In the second P site, P(2) is bonded to two equivalent O(3) and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with two equivalent Ag(2)O6 octahedra, and corners with four equivalent Fe(1)O6 octahedra.

In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mn(1), one Fe(1), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mn(1), two equivalent Ag(2), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mn(1), one Fe(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Fe(1), two equivalent Ag(1), and one P(1) atom.
