LiNO2 crystallizes in the orthorhombic Imm2 space group. Li(1) is bonded to one N(1) and six equivalent O(1) atoms to form distorted LiNO6 pentagonal bipyramids that share corners with eight equivalent Li(1)NO6 pentagonal bipyramids, corners with two equivalent O(1)Li3N tetrahedra, and edges with two equivalent Li(1)NO6 pentagonal bipyramids. N(1) is bonded in a trigonal planar geometry to one Li(1) and two equivalent O(1) atoms. O(1) is bonded to three equivalent Li(1) and one N(1) atom to form distorted OLi3N tetrahedra that share  a cornercorner with one Li(1)NO6 pentagonal bipyramid, corners with twelve equivalent O(1)Li3N tetrahedra, and edges with two equivalent O(1)Li3N tetrahedra.

The Li(1)-N(1) bond length is 2.32 Å. There are four shorter (2.26 Å) and two longer (2.33 Å) Li(1)-O(1) bond lengths. N(1) is bonded in a trigonal planar geometry to one Li(1) and two equivalent O(1) atoms. Both N(1)-O(1) bond lengths are 1.27 Å. O(1) is bonded to three equivalent Li(1) and one N(1) atom to form distorted OLi3N tetrahedra that share  a cornercorner with one Li(1)NO6 pentagonal bipyramid, corners with twelve equivalent O(1)Li3N tetrahedra, and edges with two equivalent O(1)Li3N tetrahedra.
