Sb Pt Pt Pt F
(Pt3Sb)2F2 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. The structure consists of three hydrofluoric acid atoms inside a Pt3Sb framework. In the Pt3Sb framework, Pt(1) is bonded in a linear geometry to two equivalent Sb(1) atoms. There is one shorter (2.42 Å) and one longer (2.56 Å) Pt(1)-Sb(1) bond length. Sb(1) is bonded to six equivalent Pt(1) atoms to form corner-sharing SbPt6 octahedra. The corner-sharing octahedra are not tilted.
