The compound described by PtBiSb is Ilmenite-like structured and crystallizes in the cubic P2_13 space group. Pt(1) is bonded to three equivalent Bi(1) and three equivalent Sb(1) atoms to form PtBi3Sb3 octahedra that share corners with twelve equivalent Pt(1)Bi3Sb3 octahedra, corners with three equivalent Bi(1)SbPt3 trigonal pyramids, and corners with three equivalent Sb(1)BiPt3 trigonal pyramids. The corner-sharing octahedral tilt angles range from 62-63°. Bi(1) is bonded to three equivalent Pt(1) and one Sb(1) atom to form distorted BiSbPt3 trigonal pyramids that share corners with three equivalent Pt(1)Bi3Sb3 octahedra, corners with six equivalent Bi(1)SbPt3 trigonal pyramids, and corners with nine equivalent Sb(1)BiPt3 trigonal pyramids. The corner-sharing octahedral tilt angles are 81°. Sb(1) is bonded to three equivalent Pt(1) and one Bi(1) atom to form distorted SbBiPt3 trigonal pyramids that share corners with three equivalent Pt(1)Bi3Sb3 octahedra, corners with six equivalent Sb(1)BiPt3 trigonal pyramids, and corners with nine equivalent Bi(1)SbPt3 trigonal pyramids. The corner-sharing octahedral tilt angles are 80°. is represented by the CIF file [CIF]
