The room temperature structure of SrFe/sub 12/O/sub 19/ hexagonal ferrite has been refined from X-ray single-crystal data. Structural isomorphism of the title compound with the hexagonal ferrite BaFe/sub 12/O/sub 19/ has been demonstrated. In particular, it is corroborated that the bipyramidal Fe ions have a fast diffusional motion within a quasiharmonic double-well potential as in BaFe/sub 12/O/sub 19/. Some structural differences within the R-block are found among Ba and Sr magnetoplumbites which may account for the different dynamic, magnetic, and crystallochemical behavior of both compounds.
