A series of novel and possibly synthetically accessible rigid hydrocarbon structures is computationally introduced, maintaining ultrashort non-bonded hydrogen-hydrogen (H⋅⋅⋅H) contacts smaller than 1.2 Å. These are the shortest non-bonded H⋅⋅⋅H contacts reported to date, bypassing previous world records of both experimentally observed, 1.56 Å, and computationally derived, 1.4 Å, H⋅⋅⋅H contacts in any stable molecular structure.
