RhHgSb2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Hg(1) and one Sb(2) atom. There is one shorter (2.11 Å) and one longer (3.06 Å) Rh(1)-Hg(1) bond length. The Rh(1)-Sb(2) bond length is 1.60 Å. Hg(1) is bonded in a 4-coordinate geometry to two equivalent Rh(1) and two equivalent Sb(1) atoms. There is one shorter (2.45 Å) and one longer (2.95 Å) Hg(1)-Sb(1) bond length. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 4-coordinate geometry to two equivalent Hg(1) and two equivalent Sb(2) atoms. There is one shorter (1.87 Å) and one longer (2.91 Å) Sb(1)-Sb(2) bond length. In the second Sb site, Sb(2) is bonded in a distorted single-bond geometry to one Rh(1) and two equivalent Sb(1) atoms.
