The crystal structure described by Ba4Os6O18Cl crystallizes in the cubic I23 space group. Ba(1) is bonded in a 10-coordinate geometry to three equivalent O(2), six equivalent O(1), and one Cl(1) atom. Os(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Os(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Os(1) atoms. Cl(1) is bonded in a tetrahedral geometry to four equivalent Ba(1) atoms. is represented by the CIF file [CIF]
