The material structure described by Li2Ti2AsPO10 crystallizes in the orthorhombic Pmc2_1 space group. Li(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom to form distorted LiO6 octahedra that share  a cornercorner with one Ti(2)O6 octahedra, corners with two equivalent As(1)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, and  a faceface with one Ti(2)O6 octahedra. The corner-sharing octahedral tilt angles are 61°. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 6-coordinate geometry to one O(6), one O(7), two equivalent O(1), and two equivalent O(3) atoms. In the second Ti site, Ti(2) is bonded to one O(5), one O(8), two equivalent O(2), and two equivalent O(4) atoms to form distorted TiO6 octahedra that share corners with two equivalent Li(1)O6 octahedra, corners with two equivalent Ti(2)O6 octahedra, corners with two equivalent As(1)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, and faces with two equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-61°. As(1) is bonded to one O(5), one O(8), and two equivalent O(3) atoms to form AsO4 tetrahedra that share corners with two equivalent Ti(2)O6 octahedra and corners with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-57°. P(1) is bonded to one O(6), one O(7), and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with two equivalent Ti(2)O6 octahedra and corners with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-57°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Ti(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one Ti(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Li(1), one Ti(2), and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Ti(2) and one As(1) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Ti(1) and one P(1) atom. In the seventh O site, O(7) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1), one Ti(1), and one P(1) atom. In the eighth O site, O(8) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li(1), one Ti(2), and one As(1) atom. is represented by the CIF file [CIF]
