The material described by Cs7O crystallizes in the hexagonal P-6m2 space group. There are seven inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 12-coordinate geometry to two equivalent Cs(1), two equivalent Cs(3), two equivalent Cs(4), two equivalent Cs(7), and four equivalent Cs(2) atoms. In the second Cs site, Cs(2) is bonded in a single-bond geometry to two equivalent Cs(1) and one O(1) atom. In the third Cs site, Cs(3) is bonded in a see-saw-like geometry to two equivalent Cs(1) and two equivalent Cs(5) atoms. In the fourth Cs site, Cs(4) is bonded in a see-saw-like geometry to two equivalent Cs(1) and two equivalent Cs(5) atoms. In the fifth Cs site, Cs(5) is bonded in an L-shaped geometry to two equivalent Cs(3), two equivalent Cs(4), and two equivalent O(1) atoms. In the sixth Cs site, Cs(6) is bonded in a distorted T-shaped geometry to three equivalent O(1) atoms. In the seventh Cs site, Cs(7) is bonded in a 6-coordinate geometry to six equivalent Cs(1) atoms. O(1) is bonded to two equivalent Cs(2), two equivalent Cs(5), and two equivalent Cs(6) atoms to form face-sharing OCs6 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
