KBeOsPb crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to one Be(1), four equivalent Os(1), and three equivalent Pb(1) atoms. The K(1)-Be(1) bond length is 1.71 Å. There are three shorter (2.86 Å) and one longer (3.39 Å) K(1)-Os(1) bond length. All K(1)-Pb(1) bond lengths are 3.02 Å. Be(1) is bonded in a single-bond geometry to one K(1), three equivalent Os(1), and three equivalent Pb(1) atoms. All Be(1)-Os(1) bond lengths are 3.02 Å. All Be(1)-Pb(1) bond lengths are 2.86 Å. Os(1) is bonded in a 11-coordinate geometry to four equivalent K(1), three equivalent Be(1), and four equivalent Pb(1) atoms. There are three shorter (2.86 Å) and one longer (3.39 Å) Os(1)-Pb(1) bond length. Pb(1) is bonded in a 10-coordinate geometry to three equivalent K(1), three equivalent Be(1), and four equivalent Os(1) atoms.
