PtSb2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. Pt(1) is bonded to six equivalent Sb(1) atoms to form PtSb6 octahedra that share corners with twelve equivalent Pt(1)Sb6 octahedra and corners with six equivalent Sb(1)SbPt3 trigonal pyramids. The corner-sharing octahedral tilt angles are 63°. Sb(1) is bonded to three equivalent Pt(1) and one Sb(1) atom to form distorted SbSbPt3 trigonal pyramids that share corners with three equivalent Pt(1)Sb6 octahedra and corners with fifteen equivalent Sb(1)SbPt3 trigonal pyramids. The corner-sharing octahedral tilt angles are 80°.
