Materials Data on Na2HgPb by Materials Project
Na2HgPb crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Na is bonded in a 2-coordinate geometry to four equivalent Hg and four equivalent Pb atoms. There are two shorter (3.47 Å) and two longer (3.69 Å) Na–Hg bond lengths. There are a spread of Na–Pb bond distances ranging from 3.23–3.60 Å. Hg is bonded to eight equivalent Na, two equivalent Hg, and two equivalent Pb atoms to form a mixture of distorted face, edge, and corner-sharing HgNa8Hg2Pb2 cuboctahedra. Both Hg–Hg bond lengths are 3.08 Å. Both Hg–Pb bond lengths are 3.05 Å. Pb is bonded in a 10-coordinate geometry to eight equivalent Na and two equivalent Hg atoms.
