The corner-sharing octahedra tilt angles range from 37–41°. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra, corners with two equivalent FeO6 octahedra, a cornercorner with one FeO6 pentagonal pyramid, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedra tilt angles range from 44–58°. There are a spread of P–O bond distances ranging from 1.52–1.58 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra, corners with two equivalent FeO6 octahedra, a cornercorner with one FeO6 pentagonal pyramid, and an edgeedge with one FeO6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 48–55°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Fe3+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Fe3+, one Sb3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Fe3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Fe3+ and one P5+ atom.
