The material described by Na3Os crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted trigonal planar geometry to three equivalent Os(1) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to four equivalent Os(1) atoms. Os(1) is bonded in a 10-coordinate geometry to four equivalent Na(2) and six equivalent Na(1) atoms. is represented by the CIF card [CIF]
