The crystal structure described by Sm4Rh6Pb19 crystallizes in the cubic I23 space group. Sm(1) is bonded in a 10-coordinate geometry to one Pb(2), three equivalent Pb(1), and six equivalent Pb(3) atoms. Rh(1) is bonded in a 7-coordinate geometry to one Rh(1), two equivalent Pb(1), and four equivalent Pb(3) atoms. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and two equivalent Rh(1) atoms. In the second Pb site, Pb(2) is bonded in a tetrahedral geometry to four equivalent Sm(1) atoms. In the third Pb site, Pb(3) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and two equivalent Rh(1) atoms. is represented by the CIF file [CIF]
