Lattice points in a crystal lattice are joined together by straight lines. By joining the lattice points with straight lines the geometry of the crystal lattice is formed. Unit Cell: The smallest portion of a crystal lattice is called Unit Cell. By repeating in different directions unit cell ge...

Crystal - Bonds, Structure, Lattice: The properties of a solid can usually be predicted from the valence and bonding preferences of its constituent atoms. Four main bonding types are discussed here: ionic, covalent, metallic, and molecular. Hydrogen-bond

Therefore, it is sufficient to give the a and c lattice parameters for the descriptioion of the hexagonal lattice. Hexagonal unit cell The unit cell parameters are: a = b ≠ c α = β = 90° γ = 120° The volume of the hexagonal unit cell is given by V = a2c sin(60°) ...
A space lattice, two possible unit cells, and the environment of a point Screw axes combine the rotation of an ordinary symmetry axis with a translation parallel to it and equal to a fraction of the unit distance in this direction. If screw axes are present in crystals, it is clear that...
This chapter discusses lattice geometry and crystal symmetry. In defining lattice planes and other geometrical features, one can revert for simplicity to the space lattice, assuming that each lattice point in reality corresponds with a unit atomic group, for example, its center of gravity. A ...
