Mn3SbO8 is trigonal omega-derived structured and crystallizes in the tetragonal P4_32_12 space group. There are two inequivalent Mn sites. In the first Mn site, 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 edges with two equivalent Sb(1)O6 octahedra and edges with four equivalent Mn(2)O6 octahedra. In the second Mn site, Mn(2) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form MnO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with two equivalent Sb(1)O6 octahedra. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form SbO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra and edges with four equivalent Mn(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mn(1), one Mn(2), and one Sb(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Mn(1), one Mn(2), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Mn(1) and two equivalent Mn(2) atoms. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Mn(2) and one Sb(1) atom.
