The compound described by Ba3Sb4O crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted single-bond geometry to two equivalent Sb(1), two equivalent Sb(2), two equivalent Sb(3), two equivalent Sb(4), and one O(1) atom. In the second Ba site, Ba(2) is bonded in a distorted L-shaped geometry to one Sb(1), one Sb(2), two equivalent Sb(3), two equivalent Sb(4), and two equivalent O(1) atoms. In the third Ba site, Ba(3) is bonded in a single-bond geometry to two equivalent Sb(1), two equivalent Sb(2), two equivalent Sb(3), two equivalent Sb(4), and one O(1) atom. There are four inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 7-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), one Sb(2), and one Sb(3) atom. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), one Sb(1), and one Sb(4) atom. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), two equivalent Ba(3), one Sb(1), and one Sb(4) atom. In the fourth Sb site, Sb(4) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), two equivalent Ba(3), one Sb(2), and one Sb(3) atom. O(1) is bonded to one Ba(1), one Ba(3), and two equivalent Ba(2) atoms to form edge-sharing OBa4 tetrahedra. is represented by the CIF card [CIF]
