LaCrSb3 crystallizes in the orthorhombic Pbcm space group. La(1) is bonded in a 9-coordinate geometry to one Sb(1), four equivalent Sb(2), and four equivalent Sb(3) atoms. Cr(1) is bonded to two equivalent Sb(2) and four equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing CrSb6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to one La(1), four equivalent Cr(1), and one Sb(2) atom. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to four equivalent La(1), two equivalent Cr(1), and one Sb(1) atom. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(3) atoms.
LaCrSb3 crystallizes in the orthorhombic Pbcm space group. La(1) is bonded in a 9-coordinate geometry to one Sb(1), four equivalent Sb(2), and four equivalent Sb(3) atoms. The La(1)-Sb(1) bond length is 3.37 Å. There are a spread of La(1)-Sb(2) bond distances ranging from 3.33-3.40 Å. All La(1)-Sb(3) bond lengths are 3.37 Å. Cr(1) is bonded to two equivalent Sb(2) and four equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing CrSb6 octahedra. The corner-sharing octahedral tilt angles are 46°. Both Cr(1)-Sb(2) bond lengths are 2.79 Å. There are two shorter (2.74 Å) and two longer (2.75 Å) Cr(1)-Sb(1) bond lengths. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to one La(1), four equivalent Cr(1), and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 3.20 Å. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to four equivalent La(1), two equivalent Cr(1), and one Sb(1) atom. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Sb(3) atoms. There are two shorter (3.11 Å) and two longer (3.16 Å) Sb(3)-Sb(3) bond lengths.
