Triclinic
A triclinic crystal is shaped almost like a rectangle. It is slightly bent, though. Copper sulfate makes triclinic crystals. It is the least symmetric (meaning that both sides are not very similar).
. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system.
