Hg Mo Rh Rh
MoRh2Hg crystallizes in the triclinic P1 space group. Mo(1) is bonded in a 1-coordinate geometry to one Rh(1), one Rh(2), and two equivalent Hg(1) atoms. The Mo(1)-Rh(1) bond length is 1.57 Å. The Mo(1)-Rh(2) bond length is 1.97 Å. There is one shorter (2.46 Å) and one longer (2.82 Å) Mo(1)-Hg(1) bond length. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Mo(1), one Rh(2), and two equivalent Hg(1) atoms. The Rh(1)-Rh(2) bond length is 1.54 Å. There is one shorter (2.85 Å) and one longer (3.11 Å) Rh(1)-Hg(1) bond length. In the second Rh site, Rh(2) is bonded in a 2-coordinate geometry to one Mo(1), one Rh(1), and two equivalent Hg(1) atoms. There is one shorter (2.85 Å) and one longer (3.11 Å) Rh(2)-Hg(1) bond length. Hg(1) is bonded in a 8-coordinate geometry to two equivalent Mo(1), two equivalent Rh(1), two equivalent Rh(2), and two equivalent Hg(1) atoms. Both Hg(1)-Hg(1) bond lengths are 2.82 Å.
