The structure described by Ba5(OsO5)3NO3 crystallizes in the hexagonal P6_3cm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 10-coordinate geometry to one O(4), two equivalent O(2), three equivalent O(1), and four equivalent O(3) atoms. In the second Ba site, Ba(2) is bonded in a 9-coordinate geometry to three equivalent O(3) and six equivalent O(2) atoms. Os(1) is bonded in a distorted trigonal bipyramidal geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. N(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one N(1) atom. In the second O site, O(2) is bonded to one Ba(1), two equivalent Ba(2), and one Os(1) atom to form a mixture of distorted corner and edge-sharing OBa3Os tetrahedra. In the third O site, O(3) is bonded to one Ba(2), two equivalent Ba(1), and one Os(1) atom to form a mixture of distorted corner and edge-sharing OBa3Os tetrahedra. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Ba(1) and one Os(1) atom. is represented by the CIF card [CIF]
