TaRh4Pb crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 7-coordinate geometry to one Rh(2) and six equivalent Rh(1) atoms. The Ta(1)-Rh(2) bond length is 3.05 Å. All Ta(1)-Rh(1) bond lengths are 2.81 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to two equivalent Ta(1), one Rh(2), two equivalent Rh(1), and one Pb(1) atom. The Rh(1)-Rh(2) bond length is 1.40 Å. Both Rh(1)-Rh(1) bond lengths are 0.81 Å. The Rh(1)-Pb(1) bond length is 1.75 Å. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to one Ta(1), three equivalent Rh(1), and three equivalent Pb(1) atoms. All Rh(2)-Pb(1) bond lengths are 3.25 Å. Pb(1) is bonded in a 6-coordinate geometry to three equivalent Rh(1) and three equivalent Rh(2) atoms.
