SrEu(PtP)2 is hexagonal omega structure-derived structured and crystallizes in the trigonal P-3m1 space group. Sr(1) is bonded to six equivalent Pt(1) and six equivalent P(1) atoms to form SrP6Pt6 cuboctahedra that share edges with twelve equivalent Eu(1)P6Pt6 cuboctahedra, faces with two equivalent Eu(1)P6Pt6 cuboctahedra, and faces with six equivalent Sr(1)P6Pt6 cuboctahedra. Eu(1) is bonded to six equivalent Pt(1) and six equivalent P(1) atoms to form EuP6Pt6 cuboctahedra that share edges with twelve equivalent Sr(1)P6Pt6 cuboctahedra, faces with two equivalent Sr(1)P6Pt6 cuboctahedra, and faces with six equivalent Eu(1)P6Pt6 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), three equivalent Eu(1), and three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), three equivalent Eu(1), and three equivalent Pt(1) atoms.
