✦ Synopsis
The authors regret that this article was published with errors in the indexing of one of the electron diffraction patterns. The intensity profile for the diffraction rings in Fig. 3b shows that the peak intensities decrease in the following order: (1 1 1) > (2 0 0) > (2 2 0). On the basis of simulated patterns for several fcc-type crystal structures, the intensity distribution is consistent with a defective antifluorite-type structure and not a NaCl-type structure as stated in the paper. Both structures are similar in that the O ions occupy fcc lattice positions; however, in the defective antifluorite structure the Mn cations randomly occupy some of the tetrahedral interstices instead of the octahedral sites as in the NaCl-type structure. Previous work by one of the authors showed that MnO 2 prepared from a sodium citrate-containing solution also had a similar antifluorite-type structure [Ref. 47 in the paper].
