The crystal structure described by Li2Ni3Si3O10 is Aluminum carbonitride-derived structured and crystallizes in the monoclinic C2/c space group. Li(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted LiO5 square pyramids that share  a cornercorner with one Si(1)O4 tetrahedra, corners with three equivalent Si(2)O4 tetrahedra,  an edgeedge with one Ni(2)O6 octahedra,  an edgeedge with one Li(1)O5 square pyramid, and  an edgeedge with one Si(1)O4 tetrahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms. In the second Ni site, Ni(2) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form NiO6 octahedra that share corners with two equivalent Si(1)O4 tetrahedra, edges with two equivalent Li(1)O5 square pyramids, and edges with two equivalent Si(1)O4 tetrahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form SiO4 tetrahedra that share  a cornercorner with one Ni(2)O6 octahedra,  a cornercorner with one Li(1)O5 square pyramid,  a cornercorner with one Si(2)O4 tetrahedra,  an edgeedge with one Ni(2)O6 octahedra, and  an edgeedge with one Li(1)O5 square pyramid. The corner-sharing octahedral tilt angles are 61°. In the second Si site, Si(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with six equivalent Li(1)O5 square pyramids and corners with two equivalent Si(1)O4 tetrahedra. There are five inequivalent O sites.
