The crystal structure described by Cs2Sb crystallizes in the orthorhombic Pnma space group. There are four inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 5-coordinate geometry to three equivalent Sb(1) and three equivalent Sb(2) atoms. In the second Cs site, Cs(2) is bonded in a 3-coordinate geometry to three equivalent Sb(1) and three equivalent Sb(2) atoms. In the third Cs site, Cs(3) is bonded in a 4-coordinate geometry to one Sb(1) and three equivalent Sb(2) atoms. In the fourth Cs site, Cs(4) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 11-coordinate geometry to one Cs(3), three equivalent Cs(1), three equivalent Cs(2), three equivalent Cs(4), and one Sb(2) atom. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to three equivalent Cs(1), three equivalent Cs(2), three equivalent Cs(3), and one Sb(1) atom. is represented by the CIF card [CIF]
