Monoclinic crystal system

Hence two pairs of vectors are perpendicular (meet at right angles), while the third pair makes an angle other than 90°.

For the base-centered monoclinic lattice, the primitive cell has the shape of an oblique rhombic prism;[1] it can be constructed because the two-dimensional centered rectangular base layer can also be described with primitive rhombic axes.

The table below organizes the space groups of the monoclinic crystal system by crystal class.

It lists the International Tables for Crystallography space group numbers,[2] followed by the crystal class name, its point group in Schoenflies notation, Hermann–Mauguin (international) notation, orbifold notation, and Coxeter notation, type descriptors, mineral examples, and the notation for the space groups.

The three monoclinic hemimorphic space groups are as follows: The four monoclinic hemihedral space groups include The only monoclinic Bravais lattice in two dimensions is the oblique lattice.
