Preferred Label : hexagonal graphite;
IUPAC definition : The thermodynamically stable form of graphite with an ABAB stacking sequence of the
graphene layers. The exact crystallographic description of this allotropic form is
given by the space group d6h4 - P63/mmc (unit cell constants: a 245.6 pm, c 670.8
pm). Hexagonal graphite is thermodynamically stable below approximately 2600 K and
6 GPa.;
Scope note : the use of the term graphite instead of the more exact term hexagonal graphite may
be tolerated in view of the minor importance of rhombohedral graphite, the other allotropic
form.;
