The crystal structure described by HoCd2 crystallizes in the trigonal P-3m1 space group. Ho(1) is bonded to two equivalent Ho(1) and six equivalent Cd(1) atoms to form HoHo2Cd6 hexagonal bipyramids that share corners with two equivalent Ho(1)Ho2Cd6 hexagonal bipyramids, corners with six equivalent Cd(1)Ho3Cd5 hexagonal bipyramids, edges with six equivalent Ho(1)Ho2Cd6 hexagonal bipyramids, and edges with eighteen equivalent Cd(1)Ho3Cd5 hexagonal bipyramids. Cd(1) is bonded to three equivalent Ho(1) and five equivalent Cd(1) atoms to form distorted CdHo3Cd5 hexagonal bipyramids that share corners with three equivalent Ho(1)Ho2Cd6 hexagonal bipyramids, corners with five equivalent Cd(1)Ho3Cd5 hexagonal bipyramids, edges with nine equivalent Ho(1)Ho2Cd6 hexagonal bipyramids, and edges with fifteen equivalent Cd(1)Ho3Cd5 hexagonal bipyramids. is represented by the CIF file [CIF]
