The crystal structure described by NaHg3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a body-centered cubic geometry to six equivalent Hg(2) and eight equivalent Hg(1) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded to four equivalent Na(1) and four equivalent Hg(2) atoms to form a mixture of distorted edge, face, and corner-sharing HgNa4Hg4 tetrahedra. In the second Hg site, Hg(2) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
