SrRh2Pb crystallizes in the trigonal R3m space group. Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent Rh(1), six equivalent Rh(2), and four equivalent Pb(1) atoms. There is one shorter (2.94 Å) and three longer (3.06 Å) Sr(1)-Rh(1) bond lengths. There are three shorter (3.46 Å) and three longer (3.53 Å) Sr(1)-Rh(2) bond lengths. There are three shorter (3.02 Å) and one longer (3.06 Å) Sr(1)-Pb(1) bond length. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to four equivalent Sr(1) and four equivalent Rh(2) atoms to form distorted RhSr4Rh4 tetrahedra that share corners with eight equivalent Pb(1)Sr4Rh4 tetrahedra, edges with twelve equivalent Rh(1)Sr4Rh4 tetrahedra, and faces with six equivalent Pb(1)Sr4Rh4 tetrahedra. There are three shorter (3.02 Å) and one longer (3.06 Å) Rh(1)-Rh(2) bond length. In the second Rh site, Rh(2) is bonded in a 14-coordinate geometry to six equivalent Sr(1), four equivalent Rh(1), and four equivalent Pb(1) atoms. There are three shorter (3.02 Å) and one longer (3.06 Å) Rh(2)-Pb(1) bond length. Pb(1) is bonded to four equivalent Sr(1) and four equivalent Rh(2) atoms to form distorted PbSr4Rh4 tetrahedra that share corners with eight equivalent Rh(1)Sr4Rh4 tetrahedra, edges with twelve equivalent Pb(1)Sr4Rh4 tetrahedra, and faces with six equivalent Rh(1)Sr4Rh4 tetrahedra.
