What is it about?

It's one of the most strange chromium diarsenate crystals. Containing Cr(III), the expected color should be green. The phase is PINK ! The association of the cesium (I) and chromium (III) is probably for some thing.

Why is it important?

Endowed with an open anionic framework and large tunnel, this compound can be a potential good candidate in the mineral semiconductors list.


Trying to replace partially the large cesium cation by a smaller one can improve the ionic conduction behavior.
