LiTiCPO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one TiO6 pentagonal pyramid, a cornercorner with one PO4 tetrahedra, and an edgeedge with one TiO6 pentagonal pyramid. There are a spread of Li–O bond distances ranging from 1.95–2.18 Å. Ti4+ is bonded to six O2- atoms to form TiO6 pentagonal pyramids that share a cornercorner with one LiO4 tetrahedra, corners with four equivalent PO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Ti–O bond distances ranging from 1.92–2.03 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.23–1.34 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent TiO6 pentagonal pyramids and a cornercorner with one LiO4 tetrahedra. There is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the second O2- site, O2- is bonded in a T-shaped geometry to one Li1+, one Ti4+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Ti4+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ti4+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one C4+ atom.
