Figure 4. Powder X-ray diffraction pattern of the decomposition residue of precursor 1 at 310 oC and the Le Bail fit for the cubic unit cell (Sp. gr. Fd-3m) with a = 8.1170(1) Å. The black and blue curves are the experimental and calculated patterns, respectively. The grey line is the difference curve. Theoretical peak positions are shown as blue bars at the bottom.
