The structure described by InPb4Sb3O13 crystallizes in the trigonal R3m space group. In(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form InO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-50°. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to one O(5), three equivalent O(2), and three equivalent O(4) atoms to form distorted PbO7 hexagonal pyramids that share edges with six equivalent Sb(1)O6 octahedra. In the second Pb site, Pb(2) is bonded in a 7-coordinate geometry to one O(2), one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms. Sb(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent In(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and edges with two equivalent Pb(1)O7 hexagonal pyramids. The corner-sharing octahedral tilt angles range from 42-50°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a tetrahedral geometry to one Pb(1) and three equivalent Pb(2) atoms. In the second O site, O(1) is bonded in a 4-coordinate geometry to one In(1), two equivalent Pb(2), and one Sb(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to one Pb(1), one Pb(2), and two equivalent Sb(1) atoms. In the fourth O site, O(3) is bonded in a 4-coordinate geometry to one In(1), two equivalent Pb(2), and one Sb(1) atom. In the fifth O site, O(4) is bonded in a 2-coordinate geometry to one Pb(1), one Pb(2), and two equivalent Sb(1) atoms. is represented by the CIF card [CIF]
