The structure described by Mn2Bi3Sb3O14 crystallizes in the trigonal R-3m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 55°. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form distorted MnO8 hexagonal bipyramids that share edges with six equivalent Sb(1)O6 octahedra. Bi(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. Sb(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and edges with two equivalent Mn(2)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 43-55°. There are three inequivalent O sites. In the first O site, O(3) is bonded to one Mn(1), two equivalent Bi(1), and one Sb(1) atom to form distorted OMnBi2Sb tetrahedra that share corners with two equivalent O(1)MnBi3 tetrahedra, corners with eight equivalent O(3)MnBi2Sb tetrahedra,  an edgeedge with one O(1)MnBi3 tetrahedra, and edges with two equivalent O(3)MnBi2Sb tetrahedra. In the second O site, O(1) is bonded to one Mn(2) and three equivalent Bi(1) atoms to form OMnBi3 tetrahedra that share corners with four equivalent O(1)MnBi3 tetrahedra, corners with six equivalent O(3)MnBi2Sb tetrahedra, and edges with three equivalent O(3)MnBi2Sb tetrahedra. In the third O site, O(2) is bonded in a 4-coordinate geometry to one Mn(2), one Bi(1), and two equivalent Sb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
