IrAg2Hg is beta Plutonium-derived structured and crystallizes in the triclinic P1 space group. Ir(1) is bonded in a 12-coordinate geometry to two equivalent Ir(1), two equivalent Ag(1), four equivalent Ag(2), and four equivalent Hg(1) atoms. Both Ir(1)-Ir(1) bond lengths are 2.91 Å. There is one shorter (2.56 Å) and one longer (2.81 Å) Ir(1)-Ag(1) bond length. There are a spread of Ir(1)-Ag(2) bond distances ranging from 2.87-3.33 Å. There are a spread of Ir(1)-Hg(1) bond distances ranging from 2.57-3.12 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to two equivalent Ir(1), two equivalent Ag(1), four equivalent Ag(2), and two equivalent Hg(1) atoms. Both Ag(1)-Ag(1) bond lengths are 2.91 Å. There are a spread of Ag(1)-Ag(2) bond distances ranging from 2.55-3.31 Å. There is one shorter (2.80 Å) and one longer (3.02 Å) Ag(1)-Hg(1) bond length. In the second Ag site, Ag(2) is bonded in a 12-coordinate geometry to four equivalent Ir(1), two equivalent Ag(2), four equivalent Ag(1), and two equivalent Hg(1) atoms. Both Ag(2)-Ag(2) bond lengths are 2.91 Å. There is one shorter (2.80 Å) and one longer (3.02 Å) Ag(2)-Hg(1) bond length. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Ir(1), two equivalent Ag(1), two equivalent Ag(2), and two equivalent Hg(1) atoms. Both Hg(1)-Hg(1) bond lengths are 2.91 Å.
