WebTetrahedral amorphous carbon films have been a subject of investigation during the past decade due to their unique properties, which are found to be between those of diamond and graphite. Most of the synthetic processes require relatively drastic conditions, and the carbon source may be obtained by ionization, ion sputtering, or laser ablation. WebGraphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets. Graphite thus crystallizes in the hexagonal system, in contrast to the same element crystallizing in the octahedral or tetrahedral system as diamond. What is the crystal structure of graphite and diamond?

The Carbon Chemistry and Crystal Structure of Diamonds

WebMore generally, when a carbon atom is bonded to four other atoms, the molecule (or part of a molecule) will take on a tetrahedral shape similar to that of methane. This happens because the electron pairs that make up the bonds repel each other, and the shape that maximizes their distance from each other is a tetrahedron.
