PtSnSe is Spinel-like structured and crystallizes in the cubic P2_13 space group. Pt(1) is bonded to three equivalent Sn(1) and three equivalent Se(1) atoms to form PtSn3Se3 octahedra that share corners with twelve equivalent Pt(1)Sn3Se3 octahedra, corners with three equivalent Sn(1)Pt3Se tetrahedra, and corners with three equivalent Se(1)SnPt3 tetrahedra. The corner-sharing octahedral tilt angles range from 63-64°. Sn(1) is bonded to three equivalent Pt(1) and one Se(1) atom to form SnPt3Se tetrahedra that share corners with three equivalent Pt(1)Sn3Se3 octahedra, corners with six equivalent Sn(1)Pt3Se tetrahedra, and corners with nine equivalent Se(1)SnPt3 tetrahedra. The corner-sharing octahedral tilt angles are 79°. Se(1) is bonded to three equivalent Pt(1) and one Sn(1) atom to form SeSnPt3 tetrahedra that share corners with three equivalent Pt(1)Sn3Se3 octahedra, corners with six equivalent Se(1)SnPt3 tetrahedra, and corners with nine equivalent Sn(1)Pt3Se tetrahedra. The corner-sharing octahedral tilt angles are 79°.
