The Close-Packed Rhombohedral (abbreviated CPR in this article) is more commonly known as the Samarium-type crystal, because Sm is the first element to display this crystal structure. Technically,...

The Double Hexagonal Close-Packed (DHCP) crystal structure is another close-packed, hexagonal crystal structure; however, this is not a very common crystal structure, so I’m assuming if you’re...
The triclinic Bravais lattice is the most general Bravais lattice, with no symmetry requirements. For this reason, it is sometimes called the “asymmetric” lattice or crystal structure. Triclinic...
The monoclinic unit cell has three lattice parameters a, b, and c that each have different lengths; two vector angles α and γ are at 90º to each other, and the third vector angle β is not....

The orthorhombic cell looks like a box with 3 different edge lengths. Base-centering means there is an extra lattice point at two opposite faces, which I will call the “top” and...
