In the first Fe3+ site, Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with three equivalent FeO6 octahedra, a cornercorner with one FeO4 tetrahedra, edges with three equivalent BaCl3O9 cuboctahedra, and a faceface with one BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 11°. There is one shorter (1.84 Å) and three longer (1.89 Å) Fe–O bond length. In the second Fe3+ site, Fe3+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All Fe–O bond lengths are 1.85 Å. In the third Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent FeO4 tetrahedra, faces with four BaCl3O9 cuboctahedra, and a faceface with one PtO6 octahedra. There are three shorter (1.98 Å) and three longer (2.14 Å) Fe–O bond lengths. In the fourth Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent BaO12 cuboctahedra and a faceface with one PtO6 octahedra. There are three shorter (2.02 Å) and three longer (2.11 Å) Fe–O bond lengths. Pt4+ is bonded to six O2- atoms to form PtO6 octahedra that share faces with three equivalent BaO12 cuboctahedra and faces with two FeO6 octahedra. There are three shorter (2.03 Å) and three longer (2.04 Å) Pt–O bond lengths. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ba2+, one Fe3+, and one Pt4+ atom to form distorted OBa4FePt octahedra that share corners with eleven OBa4FePt octahedra, a cornercorner with one ClBa5 trigonal bipyramid, edges with two equivalent OBa4FePt octahedra, and faces with six OBa4FePt octahedra. The corner-sharing octahedra tilt angles range from 0–62°. In the second O2- site, O2- is bonded to four Ba2+, one Fe3+, and one Pt4+ atom to form a mixture of distorted edge, corner, and face-sharing OBa4FePt octahedra. The corner-sharing octahedra tilt angles range from 0–61°. In the third O2- site, O2- is bonded in a linear geometry to three equivalent Ba2+, two equivalent Fe3+, and three equivalent Cl1- atoms.
