The crystal structure described by Na2HgPb crystallizes in the orthorhombic Cmcm space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent Hg(1) and four equivalent Pb(1) atoms. Hg(1) is bonded to eight equivalent Na(1), two equivalent Hg(1), and two equivalent Pb(1) atoms to form a mixture of distorted face, corner, and edge-sharing HgNa8Hg2Pb2 cuboctahedra. Pb(1) is bonded in a 10-coordinate geometry to eight equivalent Na(1) and two equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
