  1. Lattice constants, angles and volumes are in Å, ∘, and Å3, respectively. Z is the number of formula units. Supplementary Table 7, Supplementary Table 8, and Supplementary Table 9 contain the refined coordinates and relative occupancies of the three samples as obtained from Rietveld refinements.
