The crystal structure described by PtCd3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pt(1) is bonded to twelve equivalent Cd(1) atoms to form PtCd12 cuboctahedra that share corners with six equivalent Pt(1)Cd12 cuboctahedra, corners with twelve equivalent Cd(1)Cd8Pt4 cuboctahedra, edges with eighteen equivalent Cd(1)Cd8Pt4 cuboctahedra, faces with eight equivalent Pt(1)Cd12 cuboctahedra, and faces with twelve equivalent Cd(1)Cd8Pt4 cuboctahedra. Cd(1) is bonded to four equivalent Pt(1) and eight equivalent Cd(1) atoms to form distorted CdCd8Pt4 cuboctahedra that share corners with four equivalent Pt(1)Cd12 cuboctahedra, corners with fourteen equivalent Cd(1)Cd8Pt4 cuboctahedra, edges with six equivalent Pt(1)Cd12 cuboctahedra, edges with twelve equivalent Cd(1)Cd8Pt4 cuboctahedra, faces with four equivalent Pt(1)Cd12 cuboctahedra, and faces with sixteen equivalent Cd(1)Cd8Pt4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
