Question

The unit cell with crystallographic dimensions, $a\ne b\ne c$, $\alpha =\gamma =90$ and $\beta \ne 90$ is called :

• A. triclinic
• B. monoclinic
• C. orthorhombic
• D. tetragonal

Answer 1

The correct option is B monoclinic

$a\ne b\ne c,\alpha =\gamma ={90}^o,\beta \ne {90}^o$ are the dimensions of monoclinic bravais lattice.
