The structure described by Pr12Co6Pb crystallizes in the cubic Im-3 space group. Pr(1) is bonded in a 4-coordinate geometry to three equivalent Co(1) and one Pb(1) atom. Co(1) is bonded in a 7-coordinate geometry to six equivalent Pr(1) and one Co(1) atom. Pb(1) is bonded in a cuboctahedral geometry to twelve equivalent Pr(1) atoms. is represented by the CIF card [CIF]
