Observed Fourier maps: (a) split oxygen site in the central layer of the first subsystem resulting from the single-crystal X-ray diffraction data refinement of phase 2 (Lambert et al., 2001BB16) (contour steps of 1.6 e Å−3); (b) the equivalent site resulting from the present neutron powder diffraction refinement (contour steps of 1 fm Å−3); (c) the oxygen site in the CaO layer [same refinement as (b); contour steps of 5 fm Å−3].
