Os Os Rh Pb
Os2RhPb is beta Plutonium-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to three equivalent Os(2) and two equivalent Rh(1) atoms. There are a spread of Os(1)-Os(2) bond distances ranging from 2.22-2.96 Å. There is one shorter (2.38 Å) and one longer (2.81 Å) Os(1)-Rh(1) bond length. In the second Os site, Os(2) is bonded in a 10-coordinate geometry to two equivalent Os(2), three equivalent Os(1), two equivalent Rh(1), and three equivalent Pb(1) atoms. Both Os(2)-Os(2) bond lengths are 2.90 Å. There is one shorter (2.73 Å) and one longer (3.11 Å) Os(2)-Rh(1) bond length. There are a spread of Os(2)-Pb(1) bond distances ranging from 2.80-3.26 Å. Rh(1) is bonded in a 5-coordinate geometry to two equivalent Os(1), two equivalent Os(2), and two equivalent Pb(1) atoms. There is one shorter (2.17 Å) and one longer (2.48 Å) Rh(1)-Pb(1) bond length. Pb(1) is bonded in a 1-coordinate geometry to three equivalent Os(2) and two equivalent Rh(1) atoms.
