The material structure described by Li2Ni3SbO8 is Spinel-derived structured and crystallizes in the triclinic P-1 space group.

The corner-sharing octahedral tilt angles range from 56-62°. There are three inequivalent Ni sites.

In the first O site, O(1) is bonded to one Li(1), one Ni(1), one Ni(2), and one Ni(3) atom to form OLiNi3 tetrahedra that share corners with three equivalent O(1)LiNi3 tetrahedra, corners with three equivalent O(3)LiNi2Sb trigonal pyramids, corners with three equivalent O(4)LiNi2Sb trigonal pyramids,  an edgeedge with one O(3)LiNi2Sb trigonal pyramid, and  an edgeedge with one O(4)LiNi2Sb trigonal pyramid. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), one Ni(1), one Ni(2), and one Sb(1) atom. In the third O site, O(3) is bonded to one Li(1), one Ni(1), one Ni(3), and one Sb(1) atom to form distorted OLiNi2Sb trigonal pyramids that share corners with three equivalent O(1)LiNi3 tetrahedra, corners with three equivalent O(3)LiNi2Sb trigonal pyramids, corners with three equivalent O(4)LiNi2Sb trigonal pyramids,  an edgeedge with one O(1)LiNi3 tetrahedra, and  an edgeedge with one O(4)LiNi2Sb trigonal pyramid.
