For example, a base centered tetragonal is identical to a simple tetragonal cell by choosing a proper unit cell. A negative number is represented by a bar over the number.
Web the unit cell consists of lattice points that represent the locations of atoms or ions. Unit cells in two dimensions. If the unit cell is translated by all the lattice vectors expressed by eq.(1), the area of the whole lattice is covered once and only once. In the case of a rectangular two dimensional lattice the unit cell is the rectangle, whose sides are the vectors a1 and a2. Web the coordinates 1/2,1/2,1/2 describe a lattice point at the center of the cell. General theory describing oscillations around lattice equilibrium points can be found in [1]. These translation vectors connect the lattice pt at the origin to the points at the body centres.
