Low energy three-dimensional hydrocarbon crystal from cold compression of benzene
Abstract:
We demonstrate an interesting phase transition from cold compressed benzene to a fully saturated three-dimensional hydrocarbon crystal, Hex-CH. The very low transition point pressure, remarkable energetic stability and positive dynamical stability indicate that Hex-CH is a promising three-dimensional hydrocarbon crystal. As a transparent insulator and potential hard hydrocarbon material, Hex-CH is expected to be of general interest in organic chemistry, condensed matter physics and material science.

The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
