Base-Centered Orthorhombic Bravais Crystal Lattice

Orthorhomic crystals are a rectangular prism with a rectangular base.

Orthorhombic lattices are made by stretching a cubic lattice along two lattice vectors by two factors, forming a rectangular prism with a rectangular base. All three bases intersect at 90° angles and the three lattice vectors are mutually orthogonal.
