The material structure described by Pr12Ni6Pb crystallizes in the cubic Im-3 space group. Pr(1) is bonded in a 3-coordinate geometry to four equivalent Ni(1) and one Pb(1) atom. Ni(1) is bonded in a 9-coordinate geometry to eight equivalent Pr(1) and one Ni(1) atom. Pb(1) is bonded in a cuboctahedral geometry to twelve equivalent Pr(1) atoms. is represented by the CIF card [CIF]
