WebThere are 8 atoms per unit cell, and each atom is tetrahedrally coordinated so that it has 4 nearest neighbors. DC is a famously strong crystal structure, and is the structure of diamond. The diamond cubic cell belongs to space group 227 or , Strukturbericht A4, and Pearson symbol cF8. C (diamond) is the prototype for DC. WebThere are 2 atoms in the crystallographic unit cell. The Bravais lattice is hexagonal with two atoms in the basis. The lattice parameters of the conventional unit cell are: a = b; c = 1.633 a (ideal), α = 90 ∘, β = 90 ∘, γ = 120 ∘. The primitive cell of the hexagonal closed packed (hcp) lattice is given by the three lattice vectors:
