The crystal structure described by Rb2HgO2 crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded to five equivalent O(1) atoms to form a mixture of edge and corner-sharing RbO5 square pyramids. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to five equivalent Rb(1) and one Hg(1) atom to form a mixture of distorted edge and corner-sharing ORb5Hg octahedra. The corner-sharing octahedral tilt angles range from 0-15°. is represented by the CIF card [CIF]
