The material structure described by Pr2Ni2Cd crystallizes in the tetragonal P4/mbm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Cd(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Ni(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Pr(1) and four equivalent Ni(1) atoms to form a mixture of face and corner-sharing CdPr8Ni4 cuboctahedra. is represented by the CIF file [CIF]
