The material structure described by BaOsO9 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 9-coordinate geometry to one O(6), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. Os(1) is bonded in a distorted octahedral geometry to one O(4), one O(6), two equivalent O(2), and two equivalent O(3) atoms. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted water-like geometry to one Ba(1) and one O(1) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent O(5) atoms. In the third O site, O(6) is bonded in a water-like geometry to one Ba(1) and one Os(1) atom. In the fourth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ba(1) and one Os(1) atom. In the fifth O site, O(3) is bonded in a distorted water-like geometry to one Ba(1) and one Os(1) atom. In the sixth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one Os(1) atom. is represented by the CIF file [CIF]
