Beryllium (Be) mineral is expressed by a chemical formula (3BeO - Al2O3 -6SiO2), and it is revealed that the structure is hexagonal with the lattice parameters a = 0.9215 nm and c = 0.9169 nm, and with the density 2.68 g/cm3. How many chemical formula is/are there in a unit cell? What is the first nearest neighbor distance in such a crystal?
