Crystal Structure
?
In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.Face Centered Cubic (FCC)
  
?
The mono-clinic crystal structure is one of the seven lattice point groups. Here vectors of crystal have unequal lengths. Here vectors of crystal have unequal lengths and have two vectors perpendicular to the 3rd oneMonoclinic (MON)
