LaW3Sb is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. La(1) is bonded to six equivalent W(1) atoms to form LaW6 octahedra that share corners with six equivalent La(1)W6 octahedra, edges with three equivalent Sb(1)W9 cuboctahedra, and faces with four equivalent Sb(1)W9 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.28 Å) and three longer (2.65 Å) La(1)-W(1) bond lengths. W(1) is bonded in a distorted linear geometry to two equivalent La(1) and three equivalent Sb(1) atoms. There is one shorter (3.22 Å) and two longer (3.49 Å) W(1)-Sb(1) bond lengths. Sb(1) is bonded to nine equivalent W(1) atoms to form distorted SbW9 cuboctahedra that share corners with six equivalent Sb(1)W9 cuboctahedra, edges with six equivalent Sb(1)W9 cuboctahedra, edges with three equivalent La(1)W6 octahedra, and faces with four equivalent La(1)W6 octahedra.
