Types of Bravais Lattice

Cubic

• The cubic system contains three types of Bravais lattices: simple cubic, face-centered cubic and body-centered cubic. Cubic unit cells have equal sides and equal 90-degree angles.

Orthorhombic

• The orthorhombic system contains four types of Bravais lattices: simple orthorhombic, face-centered orthorhombic, body-centered orthorhombic and base-centered orthorhombic. These unit cells have three different side lengths and equal 90-degree angles.

Tetragonal

• The tetragonal system contains two types of Bravais lattices: simple tetragonal and body-centered tetragonal. These unit cells have two different side lengths and equal 90-degree angles.

Monoclinic

• The monoclinic system contains two types of Bravais lattices: simple monoclinic and base-centered monoclinic. These unit cells have three different side lengths with two 90-degree angles and one dissimilar angle.

Hexagonal

• The hexagonal Bravais lattice is the only type within this system. The unit cell has two different side lengths with two 90-degree angles and a 120-degree angle.

Triclinic

• The triclinic Bravais lattice is the only type within this system. The unit cell has three different side lengths and three different angles.

Rhombohedral

• The rhombohedral Bravais lattice is the only type within this system. The unit cell has three equal side lengths with two 90-degree angles and one dissimilar angle.
