SrRhPb4 crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 7-coordinate geometry to one Rh(1), three equivalent Pb(1), and three equivalent Pb(2) atoms. The Sr(1)-Rh(1) bond length is 3.27 Å. All Sr(1)-Pb(1) bond lengths are 3.16 Å. All Sr(1)-Pb(2) bond lengths are 3.85 Å. Rh(1) is bonded in a 4-coordinate geometry to one Sr(1) and three equivalent Pb(1) atoms. All Rh(1)-Pb(1) bond lengths are 3.27 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and three equivalent Pb(1) atoms. All Pb(2)-Pb(1) bond lengths are 2.79 Å. In the second Pb site, Pb(1) is bonded in a 3-coordinate geometry to one Sr(1), one Rh(1), one Pb(2), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 1.61 Å.
