AgMnO4 crystallizes in the monoclinic P2_1/c space group. Mn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form MnO4 tetrahedra that share corners with seven equivalent Ag(1)O7 pentagonal bipyramids. Ag(1) is bonded to one O(3), two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted AgO7 pentagonal bipyramids that share corners with two equivalent Ag(1)O7 pentagonal bipyramids, corners with seven equivalent Mn(1)O4 tetrahedra, and edges with two equivalent Ag(1)O7 pentagonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Mn(1) and two equivalent Ag(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one Ag(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Ag(1) atoms.
