Monoclinic and Triclinic Crystal Classes
 
In crystallography, the monoclinic and triclinic crystal systems for part of the 7 crystal systems.
 
In the triclinic system, the crystal is described by vectors of unequal length.  
In addition, all three vectors are not mutually orthogonal.
The triclinic lattice is the least symmetric of the 14 three-dimensional Bravais lattices
 
In the monoclinic system, the crystal is described by vectors of unequal length.
They form a rectangular prism with a parallelogram as its base. Hence two pairs of vectors are perpendicular, while the third pair makes an angle other than 90.
alpha=gamma=90 degrees, beta<>90 degrees.
