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.

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. There are four shorter (3.24 Å) and two longer (3.27 Å) Eu(1)-Pt(1) bond lengths. There are four shorter (3.23 Å) and two longer (3.28 Å) Eu(1)-As(1) bond lengths. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent As(1) atoms. There are two shorter (2.46 Å) and one longer (2.47 Å) Pt(1)-As(1) bond length. As(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent Pt(1) atoms.
