OsRh2Pb crystallizes in the trigonal R3m space group. Os(1) is bonded in a 10-coordinate geometry to three equivalent Rh(2), four equivalent Rh(1), and three equivalent Pb(1) atoms. All Os(1)-Rh(2) bond lengths are 2.71 Å. There is one shorter (2.29 Å) and three longer (2.97 Å) Os(1)-Rh(1) bond lengths. All Os(1)-Pb(1) bond lengths are 2.71 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to four equivalent Os(1), one Rh(2), and three equivalent Pb(1) atoms. The Rh(1)-Rh(2) bond length is 2.11 Å. All Rh(1)-Pb(1) bond lengths are 2.71 Å. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to three equivalent Os(1), one Rh(1), and four equivalent Pb(1) atoms. There is one shorter (2.29 Å) and three longer (2.97 Å) Rh(2)-Pb(1) bond lengths. Pb(1) is bonded in a 10-coordinate geometry to three equivalent Os(1), three equivalent Rh(1), and four equivalent Rh(2) atoms.
