The crystal structures of two 12-layered CdI2 polytypes have been determined by comparison of the observed x-ray diffraction-intensity distributions with the intensity distributions of geometrically possible structures. Their space group is P3m1 and Zhdanov symbols are (22211211) and (11123211), respectively.
Zeitschrift für Kristallographie – Crystalline Materials offers a place for researchers to present results of their crystallographic studies. The journal includes theoretical as well as experimental research. It publishes Original Papers, Letters and Review Articles in manifold areas of crystallography.
