Mg Os Os Rh
MgOs2Rh crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent Os(1) and two equivalent Rh(1) atoms. There is one shorter (2.79 Å) and one longer (2.97 Å) Mg(1)-Os(1) bond length. There is one shorter (2.24 Å) and one longer (2.46 Å) Mg(1)-Rh(1) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Os(2), and six equivalent Os(1) atoms. There is one shorter (2.27 Å) and one longer (2.49 Å) Os(1)-Os(2) bond length. There are four shorter (2.73 Å) and two longer (2.86 Å) Os(1)-Os(1) bond lengths. In the second Os site, Os(2) is bonded in a 10-coordinate geometry to two equivalent Os(1), six equivalent Os(2), and two equivalent Rh(1) atoms. There are four shorter (2.73 Å) and two longer (2.86 Å) Os(2)-Os(2) bond lengths. There is one shorter (2.94 Å) and one longer (3.12 Å) Os(2)-Rh(1) bond length. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Mg(1) and two equivalent Os(2) atoms.
