In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two CuO6 octahedra, a cornercorner with one PO4 tetrahedra, and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 53–71°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two CuO6 octahedra, a cornercorner with one PO4 tetrahedra, a cornercorner with one CuO5 trigonal bipyramid, and an edgeedge with one CuO6 octahedra. The corner-sharing octahedra tilt angles range from 36–58°. There are a spread of P–O bond distances ranging from 1.53–1.61 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two CuO6 octahedra, a cornercorner with one PO4 tetrahedra, and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 54–57°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu+2.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu+2.67+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted L-shaped geometry to one Cu+2.67+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cu+2.67+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu+2.67+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two Cu+2.67+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu+2.67+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two Cu+2.67+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu+2.67+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu+2.67+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to two Cu+2.67+ and one P5+ atom.
