Diamond structure

Diamond is a typical atomic crystals, are equiaxed, it is a duplex crystal lattice, a face-centered cubic unit cell has four carbon atoms, the four atoms are located in four diagonal space 1/4. The combination of carbon atoms in diamond is the carbon atom of the housing

Four valence electrons 2s, 2p3 hybrid form a covalent bond (sp3). Each carbon atom and four carbon atoms  Synthetic diamond by covalent, a tetrahedral carbon atom in the center, with its four other atoms covalently apex angle of a regular tetrahedron, the center angle on the carbon atom and each a carbon atom

Child sharing two valence electrons. Rod lines as a covalent bond. Therefore concluded that tetrahedral carbon atom bond Polycrystalline diamond orientation of the carbon atoms in the same are different. For example: If a valence bond point to the upper left, the other will point to the bottom right of the valence bond. Since the orientation of bond

Different, the two carbon atoms different from the surrounding situation, the surface of the cube corners and around the heart of carbon atoms is different from the case of the diagonal case four carbon atoms. Therefore, the diamond lattice structure duplex consists of two face-centered cubic Bravais unit cell along its space for

Moldings displacement 1/4 the length of the sleeve structure is made.
