The structure described by La4Os6O19 crystallizes in the orthorhombic I222 space group. La(1) is bonded in a 10-coordinate geometry to one O(1), one O(2), one O(3), one O(4), two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles range from 53-54°. In the second Os site, Os(2) is bonded to two equivalent O(3), two equivalent O(6), and two equivalent O(7) atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles range from 53-54°. In the third Os site, Os(3) is bonded to two equivalent O(1), two equivalent O(5), and two equivalent O(7) atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Os(3) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Os(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Os(2) atoms. In the fourth O site, O(4) is bonded in a tetrahedral geometry to four equivalent La(1) atoms. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent La(1), one Os(1), and one Os(3) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to two equivalent La(1), one Os(1), and one Os(2) atom. In the seventh O site, O(7) is bonded in a 4-coordinate geometry to two equivalent La(1), one Os(2), and one Os(3) atom. is represented by the CIF file [CIF]
