There are a spread of Li–O bond distances ranging from 1.95–2.43 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 trigonal bipyramids that share corners with three SbO5 square pyramids, corners with three PO4 tetrahedra, an edgeedge with one LiO5 square pyramid, and an edgeedge with one PO4 tetrahedra.

In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three SbO5 square pyramids and an edgeedge with one LiO5 square pyramid. There is two shorter (1.55 Å) and two longer (1.56 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 three SbO5 square pyramids, corners with two equivalent LiO4 tetrahedra, and an edgeedge with one LiO5 trigonal bipyramid.
