BaCo2Sn4O11 is isotypic with R-ferrite, BaTi2Fe4O11. The Co atoms fully occupy trigonal-bipyramidal sites ( ) and are disordered with Sn atoms in octa-hedral sites (.2/m symmetry), as represented in the formula BaCoSn2(Co0.34Sn0.66)4O11. Ba atoms are situated in a 12-fold coordinated site ( symmetry).
