The material described by LiO4I crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one O(1), one O(2), one O(3), and two equivalent O(4) atoms to form distorted LiO5 trigonal bipyramids that share corners with five equivalent I(1)O4 tetrahedra and  an edgeedge with one Li(1)O5 trigonal bipyramid. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Li(1) and one I(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Li(1) and one I(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Li(1) and one I(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent Li(1) and one I(1) atom. I(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form IO4 tetrahedra that share corners with five equivalent Li(1)O5 trigonal bipyramids. is represented by the CIF card [CIF]
