In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO6 octahedra, corners with three CoO6 octahedra, and an edgeedge with one CuO6 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There is two shorter (1.54 Å) and two longer (1.57 Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four CoO6 octahedra and an edgeedge with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There is two shorter (1.53 Å) and two longer (1.58 Å) P–O bond length. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two CoO6 octahedra, corners with two equivalent CuO6 octahedra, and an edgeedge with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Co+3.33+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Co+3.33+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Co+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Co+3.33+, one Cu2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co+3.33+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Co+3.33+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Co+3.33+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to one Co+3.33+, one Cu2+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Co+3.33+ and one P5+ atom.
