The crystal structure described by Os is High pressure (38.9 GPa) phase of lithium-like structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 11-coordinate geometry to five equivalent Os(1) and six equivalent Os(2) atoms. In the second Os site, Os(2) is bonded in a 11-coordinate geometry to five equivalent Os(2) and six equivalent Os(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
