The material structure described by EuPtAs is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Eu(1) is bonded to six equivalent Pt(1) and six equivalent As(1) atoms to form a mixture of face and edge-sharing EuAs6Pt6 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent Pt(1) atoms. is represented by the CIF card [CIF]
