Na2PdHg crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 1-coordinate geometry to one Na(2), one Pd(1), and three equivalent Hg(1) atoms. The Na(1)-Na(2) bond length is 2.53 Å. The Na(1)-Pd(1) bond length is 2.20 Å. There are a spread of Na(1)-Hg(1) bond distances ranging from 2.60-3.18 Å. In the second Na site, Na(2) is bonded in a 8-coordinate geometry to one Na(1), four equivalent Pd(1), and three equivalent Hg(1) atoms. There are a spread of Na(2)-Pd(1) bond distances ranging from 2.62-3.31 Å. There are a spread of Na(2)-Hg(1) bond distances ranging from 2.79-3.47 Å. Pd(1) is bonded in a 1-coordinate geometry to one Na(1) and four equivalent Na(2) atoms. Hg(1) is bonded in a 6-coordinate geometry to three equivalent Na(1) and three equivalent Na(2) atoms.
