Orthorhombic Bravais Lattices

oP	oC

The orthorhombic lattice has three orthogonal axes of order 2 imposed as symmetry constraints forcing all of the unit cell angles to 90°. The 3 independent lattice parameters are a, b, and c.

The orthorhombic lattice is either primitive or centred in one of three different ways: C-face centred, body-centred, or all-face centred. Alternative labelling of the cell axes can result in a Bravais lattice equivalent to the C-face centring, but with either A- or B-face centring.
