Structure maps, classification, and systematization of ABX(2), ABX(3), and ABX(4) halides

摘要

The criterion Delta E > = E >((AX)) - E >((BX)) enabling the systematization of structures in terms of symmetry categories was proposed for the classification of three-element ionic halides by complex/double type. The adequacy of this approach was verified by the structure maps plotted using the generalized strength parameter. The crystal-chemical properties of the structures of ABX(2), ABX(3), and ABX(4) halides were predicted.
