In the second Li1+ site, Li1+ is bonded in a distorted trigonal planar geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.72 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra, corners with four PO4 tetrahedra, a cornercorner with one CrO5 trigonal bipyramid, and an edgeedge with one CrO6 octahedra. There are a spread of Li–O bond distances ranging from 2.02–2.06 Å. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one CrO6 octahedra, corners with two equivalent LiO4 tetrahedra, and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 77°. There are a spread of Li–O bond distances ranging from 1.97–2.10 Å.
