In the following table (16.3), we list some common substances which are found in the 14 Bravais lattices. How a given substance chooses to be found in a given lattice type is determined by the sizes of the constituent particles and the detailed interactions between them.

Table 16.3 Common substances in seven crystal systems.

1	Cubic	Metal like Ni, Ag, Au, Cu, Al; Na⁺ ions in NaCl lattice [FCC] one form of Fe, V, Cr, Mo, W; CsCl, taking Cs⁺ and Cl^- together [BCC], - Polonium, Cl^- lattice in a CsCl lattice [simple cubic]

2	Hexagonal	Metallic Be, SiO_2, Mg₂SiO₄, corundum, quartz, ruby

3	Orthorhombic	Epsom salts, ancylite, sulphur, pyrite, Hg(II)chloride

4	Tetragonal	Zircon, Tellurium oxide, PbTiO₃

5	Triclinic	Pentahydrate form of Cu (II) sulphate, serandite, feldspar, n- alkanes, lysozyme crystals grown at pH 4.5
