La(SbO3)3 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(4) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 33-52°. In the second Sb site, Sb(2) is bonded to two equivalent O(3) and four equivalent O(4) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one La(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one La(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Sb(1) and one Sb(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one La(1), one Sb(1), and one Sb(2) atom.
La(SbO3)3 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(4) atoms.
