The structure described by Na3Sb is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 1-coordinate geometry to four equivalent Sb(1) atoms. In the second Na site, Na(2) is bonded in a trigonal planar geometry to three equivalent Sb(1) atoms. Sb(1) is bonded in a 11-coordinate geometry to three equivalent Na(2) and eight equivalent Na(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
