The crystal structure described by Li2HgO2 crystallizes in the tetragonal I4/mmm space group. Li(1) is bonded to five equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing LiO5 square pyramids. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to five equivalent Li(1) and one Hg(1) atom to form a mixture of distorted corner and edge-sharing OLi5Hg octahedra. The corner-sharing octahedral tilt angles range from 0-20°. is represented by the CIF file [CIF]
