Coordination of octahedral void
WebHere is a summary of the characteristics of a tetrahedral void. A single triangular void or vacant space in a crystal is surrounded by four (4) atomic spheres. Therefore, the coordination number of the tetrahedral void is also 4. In a tetrahedral void, the atom comes in contact with four atoms that are placed at four corners of a tetrahedron.
