PtGeSe is Spinel-like structured and crystallizes in the orthorhombic Pca2_1 space group. Pt(1) is bonded to three equivalent Ge(1) and three equivalent Se(1) atoms to form PtGe3Se3 octahedra that share corners with twelve equivalent Pt(1)Ge3Se3 octahedra, corners with three equivalent Ge(1)Pt3Se tetrahedra, and corners with three equivalent Se(1)GePt3 tetrahedra. The corner-sharing octahedral tilt angles range from 63-65°. Ge(1) is bonded to three equivalent Pt(1) and one Se(1) atom to form GePt3Se tetrahedra that share corners with three equivalent Pt(1)Ge3Se3 octahedra, corners with six equivalent Ge(1)Pt3Se tetrahedra, and corners with nine equivalent Se(1)GePt3 tetrahedra. The corner-sharing octahedral tilt angles range from 75-80°. Se(1) is bonded to three equivalent Pt(1) and one Ge(1) atom to form SeGePt3 tetrahedra that share corners with three equivalent Pt(1)Ge3Se3 octahedra, corners with six equivalent Se(1)GePt3 tetrahedra, and corners with nine equivalent Ge(1)Pt3Se tetrahedra. The corner-sharing octahedral tilt angles range from 78-79°.
