The structures of mcgovernite and carlfrancisite reconsidered: static disorder or ordered defects and twinning?
A reconsideration of the crystal structures of mcgovernite and carlfrancisite gives noncentrosymmetric structures with ordered planar defects instead of random site disorder in centrosymmetric ones.
