It is known that 13 among the 44 types of (Niggli) reduced cells correspond to centred monoclinic lattices. For these 13 types, the connexion is given between the reduced cell and a conventional cell. For centred lattices of monoclinic and orthorhombic symmetry, we describe the shape of the conventional cell for the different types of reduced cell. Errors are corrected in the section on Reduced Cells of the International Tables for X-ray Crystallography [Vol. I (1969), Birmingham: Kynoch Press]. |
