Among planar tetracoordinate atoms, planar tetracoordinate oxygen atoms (ptO) are rare. The present study establishes the first example of noble gas supported planar tetracoordinate oxygen atoms (ptO). High level ab initio calculations indicate that He and Ne form perfect square planar D4h ptO structures as the global minimum. Detailed electronic structure analyses reveal that the central oxygen atom is bonded through strong covalent interactions. The present finding illustrates the ability of noble gas atoms in stabilizing planar tetracoordinate oxygen atoms and will advance the understanding of unconventional chemical bonding involving oxygen.

Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.
