The compound described by PtCd3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Pt(1) is bonded to four equivalent Cd(2) and eight equivalent Cd(1) atoms to form PtCd12 cuboctahedra that share corners with four equivalent Pt(1)Cd12 cuboctahedra, edges with eight equivalent Pt(1)Cd12 cuboctahedra, edges with sixteen equivalent Cd(1)Cd8Pt4 cuboctahedra, faces with four equivalent Pt(1)Cd12 cuboctahedra, and faces with eight equivalent Cd(1)Cd8Pt4 cuboctahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to four equivalent Pt(1), four equivalent Cd(1), and four equivalent Cd(2) atoms to form distorted CdCd8Pt4 cuboctahedra that share corners with twelve equivalent Cd(1)Cd8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Cd12 cuboctahedra, edges with eight equivalent Cd(1)Cd8Pt4 cuboctahedra, faces with four equivalent Pt(1)Cd12 cuboctahedra, and faces with ten equivalent Cd(1)Cd8Pt4 cuboctahedra. In the second Cd site, Cd(2) is bonded in a distorted square co-planar geometry to four equivalent Pt(1) and eight equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
