Graphite tetrahedral structure
WebRhombohedral graphite is a thermodynamically unstable allotropic form of graphite with an ABCABC stacking sequence of the layers. The exact crystallographic description of this allotropic form is given by the space group D3d5–R3 m (unit cell constants: a = 256.6 pm, c = 1006.2 pm). See graphite Notes: Webgraphite, also called plumbago or black lead, mineral consisting of carbon. Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets. Graphite thus crystallizes …
