SbCrSe3 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to one Se(2), two equivalent Se(1), and three equivalent Se(3) atoms to form edge-sharing CrSe6 octahedra. Sb(1) is bonded in a 6-coordinate geometry to one Se(3), two equivalent Se(2), and three equivalent Se(1) atoms. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and three equivalent Sb(1) atoms. In the second Se site, Se(2) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Sb(1) atoms. In the third Se site, Se(3) is bonded in a 3-coordinate geometry to three equivalent Cr(1) and one Sb(1) atom.
SbCrSe3 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to one Se(2), two equivalent Se(1), and three equivalent Se(3) atoms to form edge-sharing CrSe6 octahedra. The Cr(1)-Se(2) bond length is 2.57 Å. Both Cr(1)-Se(1) bond lengths are 2.62 Å. There is one shorter (2.51 Å) and two longer (2.54 Å) Cr(1)-Se(3) bond lengths. Sb(1) is bonded in a 6-coordinate geometry to one Se(3), two equivalent Se(2), and three equivalent Se(1) atoms. The Sb(1)-Se(3) bond length is 3.23 Å. Both Sb(1)-Se(2) bond lengths are 2.66 Å. There is one shorter (2.68 Å) and two longer (3.30 Å) Sb(1)-Se(1) bond lengths. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and three equivalent Sb(1) atoms.
