8. Powder diffraction patterns were recorded on a Rigaku Rotaflex 250 mm radius diffractometer with Cu-anode radiation. Measurements were in reflection mode at 19°C with a step size of 0.002°. The pattern was calibrated with an internal Si standard (640A, NIST, USA).

10. The calculation was performed as follows: A stick spectrum was first calculated by using the atomic coordinates presented in Table 1 applying standard diffraction theory. Lorentzian line shapes with a width calculated from the size of the crystals using the Debye-Scherrer equation were then added. Small differences in line shape between theory and experiment are the result of the size distribution in the sample.

12. The small amount of cobalt oxide (CoO) observed in Figure 2c was formed during the heating process. The observed sharpening of the peaks is due to sintering and annealing of the crystal.
