Sn Bi Rh Pb
RhPbSnBi crystallizes in the trigonal R3m space group. Rh(1) is bonded to one Pb(1) and three equivalent Sn(1) atoms to form distorted RhSn3Pb trigonal pyramids that share  a cornercorner with one Sn(1)BiRh3Pb trigonal bipyramid, corners with three equivalent Pb(1)SnBi3Rh trigonal bipyramids, corners with six equivalent Rh(1)Sn3Pb trigonal pyramids, and edges with three equivalent Bi(1)SnPb3 trigonal pyramids. The Rh(1)-Pb(1) bond length is 2.16 Å. All Rh(1)-Sn(1) bond lengths are 2.99 Å. Pb(1) is bonded to one Rh(1), one Sn(1), and three equivalent Bi(1) atoms to form distorted PbSnBi3Rh trigonal bipyramids that share corners with six equivalent Pb(1)SnBi3Rh trigonal bipyramids,  a cornercorner with one Bi(1)SnPb3 trigonal pyramid, corners with three equivalent Rh(1)Sn3Pb trigonal pyramids, and edges with three equivalent Sn(1)BiRh3Pb trigonal bipyramids. The Pb(1)-Sn(1) bond length is 2.16 Å. All Pb(1)-Bi(1) bond lengths are 2.99 Å.
