title: R-Ferrite-type barium cobalt stannate, BaCo(2)Sn(4)O(11).
abstract: BaCo(2)Sn(4)O(11) is isotypic with R-ferrite, BaTi(2)Fe(4)O(11). 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 BaCoSn(2)(Co(0.34)Sn(0.66))(4)O(11). Ba atoms are situated in a 12-fold coordinated site ( symmetry).
