WebA crystal's lattice points are linked together by straight lines. The geometry (or shape) of the crystal is obtained by combining these points. Each of the fourteen lattices has a different geometry. Introduction to Unit Cell The most basic and least volume-consuming repeating structure of any solid material is the unit cell.

WebPrimitive unit cells are defined as unit cells with the smallest volume for a given crystal. (A crystal is a lattice and a basis at every lattice point.) To have the smallest cell volume, a primitive unit cell must contain (1) only one lattice point and (2) the minimum amount of basis constituents (e.g., the minimum number of atoms in a basis).
