In article number 1900045, Akihiro Umayahara and Massimo Nespolo present a revised classification of monoarchetypal modular structures. Chemical twins are characterized by altered coordination at the interface between modules and, depending on whether this results or not in a modification of the chemical composition, they are classified in heterochemical and isochemical. Polytypes in which the partial operations mapping the modules are ordinary space‐group operations are called Ito twins. OD structures are polytypes in which layer pairs are geometrically equivalent.
