Abstract
It is shown that the arrays formed by the majority component atoms in the structure types of SiF4 and CuAl2 are topologically equivalent and can be transformed into each other by a simple distortion of their basis clusters. The geometrical flexibility of the CuAl2 type is investigated and a structure map for the representatives of this structure type, as well as those of its derivatives BaFe2S4, TlSe, and U3Si, is presented. It is suggested that the compounds BaTe2 and SrS2 should not be counted as representatives of the CuAl2 type but form their own structure type.
