Geometrical properties of MDO polytypes and procedures for their derivation. II. OD families containing OD layers of M > 1 kinds and their MDO polytypes
Abstract
The condition for MDO polytypes formulated in paper I Dornberger-Schiff (1982). Acta Cryst. A38, 483- 491 is applied to OD structures containing OD layers of M > 1 kinds. Methods for ascertaining whether a certain polytype is an MDO polytype or not, and for deducing a complete list of MDO polytypes for any family of polytypes are given. These are applied to YCl(OH)2 and some MeX2 polytype families.
