The crystal structure described by PrCuCd crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Cd(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Cd(1) atoms. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. is represented by the CIF file [CIF]
