Ordering of the tetrahedral site vacancies in two crystals of refinedcompositions K0.93(1)Fe1.52(1)Se2 and K0.862(3)Fe1.563(4)Se2 produces afivefold expansion of the parent ThCr2Si2 unit cell in the ab plane which canaccommodate 20% vacancies on a single site within the square FeSe layer. Theiron charge state is maintained close to +2 by coupling of the level of alkalimetal and iron vacancies, producing a potential doping mechanism which canoperate at both average and local structure levels.

Cation vacancy order in the K0.8+xFe1.6-ySe2 system: five-fold cell expansion accommodates 20% tetrahedral vacancies
