Space lattice or Crystal lattice and Unit Cell. A crystalline solid has a very special structure, that gives it the unique properties of a solid. This structure is made up of repeating units which we call a unit cell. Let us study this special lattice structure in detail. Suggested Videos.
In general, a unit cell is defined by the lengths of three axes ( a, b, and c) and the angles ( α, β, and γ) between them, as illustrated in Figure 10.55. The axes are defined as being the lengths between points in the space lattice. Consequently, unit cell axes join points with identical environments.

space lattice: all points within a crystal that have identical environments. tetrahedral hole: tetrahedral space formed by four atoms or ions in a crystal. unit cell: smallest portion of a space lattice that is repeated in three dimensions to form the entire lattice
The crystal lattice is the symmetrical three-dimensional structural arrangements of atoms, ions or molecules (constituent particle) inside a crystalline solid as points. It can be defined as the geometrical arrangement of the atoms, ions or molecules of the crystalline solid as points in space.

If each such unit of atoms or atom in a crystal is replaced by a point in space, then the resultant points in space are called space lattice. Each point in space is called a lattice point and each unit of atoms or atom is called basis or pattern.

A space lattice is defined as the arrangement of infinite numbers of imaginary points in two-dimensional or three-dimensional space in which each point has identical surrounding with every other points in this arrangement. These are purely mathematical points.
