Ba5Cd2(Sb2O)2 crystallizes in the monoclinic C2/m 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), four equivalent Sb(2), and one O(1) atom. In the second Ba site, Ba(2) is bonded in a 3-coordinate geometry to one Sb(1), three equivalent Sb(2), and three equivalent O(1) atoms. In the third Ba site, Ba(3) is bonded in a distorted linear geometry to four equivalent Sb(1) and two equivalent O(1) atoms. Cd(1) is bonded in a 4-coordinate geometry to one Sb(2) and three equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), and three equivalent Cd(1) atoms. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to three equivalent Ba(2), four equivalent Ba(1), one Cd(1), and one Sb(2) atom. O(1) is bonded to one Ba(1), one Ba(3), and three equivalent Ba(2) atoms to form a mixture of corner and edge-sharing OBa5 trigonal bipyramids.
