Co Hg Hg Rh
RhCoHg2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 4-coordinate geometry to two equivalent Co(1), two equivalent Hg(2), and three equivalent Hg(1) atoms. There is one shorter (2.40 Å) and one longer (2.78 Å) Rh(1)-Co(1) bond length. There is one shorter (2.60 Å) and one longer (2.96 Å) Rh(1)-Hg(2) bond length. There are a spread of Rh(1)-Hg(1) bond distances ranging from 2.60-3.35 Å. Co(1) is bonded in a 5-coordinate geometry to two equivalent Rh(1), two equivalent Hg(2), and three equivalent Hg(1) atoms. There is one shorter (2.46 Å) and one longer (2.61 Å) Co(1)-Hg(2) bond length. There are a spread of Co(1)-Hg(1) bond distances ranging from 2.26-3.18 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 10-coordinate geometry to three equivalent Rh(1), three equivalent Co(1), two equivalent Hg(1), and two equivalent Hg(2) atoms. Both Hg(1)-Hg(1) bond lengths are 3.03 Å. There is one shorter (2.22 Å) and one longer (2.96 Å) Hg(1)-Hg(2) bond length. In the second Hg site, Hg(2) is bonded in a 5-coordinate geometry to two equivalent Rh(1), two equivalent Co(1), and two equivalent Hg(1) atoms.
