The crystal system of a compound with unit cell dimensions a=0.350,b=0.350 and c=0.500 and alpha=beta=90^(@) and gamma=120^(@) is

The crystal system of a compound with unit cell dimensions a = 0.388 , b = 0.388 and c = 0.506 nm and alpha = beta = 90^@ and gamma = 120^@ is

Which premitive unit cell has unequal edge length (a != b != c) and all axial angles different from 90^(º) ?

if a=b ne c and alpha=beta=gamma=90^(@) , the crystal system is

A line makes angles alpha,beta and gamma with the coordinate axes. If alpha+beta=90^0, then find gamma .

The regular three dimensional arrangement of points in a crystal is known as crystal lattice and the smallest repeating pattern in the lattice is called unit cell. The unit cells are characterised by the edge lengths a, b, c and the angles between them alpha, beta and gamma respectively. Based on this, there are seven crystal systems. In a cubic unit cell: a=b=c and alpha = beta=gamma=90^(@) The number of points in simple, body centred and face centred cubic cells are 1,2 and 4 respectively In both the hcp and ccp of spheres, the number of tetrahedral voids per sphere is two while the octahedral voids is one. In a face centred cubic cell, an atom at the face contributes to the unit cell
