Hexagonal

Vedclass · Answer

(B) The crystal system is determined by the unit cell parameters $a, b, c$ and the interfacial angles $\alpha, \beta, \gamma$.Given parameters are $a = b = 0.387 \ nm$,$c = 0.504 \ nm$,which implies $a = b 
eq c$.The angles are $\alpha = \beta = 90^{\circ}$ and $\gamma = 120^{\circ}$.These specific conditions ($a = b 
eq c$ and $\alpha = \beta = 90^{\circ}, \gamma = 120^{\circ}$) correspond to the Hexagonal crystal system.

The crystal system of a compound with unit cell dimensions $a = 0.387 \ nm$,$b = 0.387 \ nm$ and $c = 0.504 \ nm$ and $\alpha = \beta = 90^{\circ}$ and $\gamma = 120^{\circ}$ is:
