Distinguish between Hexagonal and Monoclinic unit cell

Q-Distinguish between Hexagonal and Monoclinic unit cell

Answer- The main difference between Hexagonal unit cells and Monoclinic unit cells are as follows:

Hexagonal unit cellMonoclinic unit cell
1.The hexagonal unit cell has a Hexagonal crystal systemThe monoclinic unit cell has a monoclinic crystal system
2.There is no parallelogram structure.There is a parallelogram structure as the base of the unit cell.
3.Hexagonal unit cells have two axes with equal lengths and one axis with unequal length (a=b≠c)Monoclinic unit cells have three axes with unequal lengths (a≠b≠c)
4.The angel α and β are equal to 90° and the γ angel is equal to 120°The angle α and γ is equal to 90° and the β angle is not equal to 90°
