The material described by NaHg is alpha iridium vanadium-like structured and crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 8-coordinate geometry to eight equivalent Hg(1) atoms. In the second Na site, Na(2) is bonded in a 8-coordinate geometry to eight equivalent Hg(1) atoms. Hg(1) is bonded in a 11-coordinate geometry to four equivalent Na(1), four equivalent Na(2), and three equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
