All data are ascii format and are labelled according to the figures in the paper.

Figure 1: Powder XRD data. Two-columns: diffraction angle (two-theta) and intensity.

Figure 5: X-ray absorption spectroscopy. Two columns: energy and normalised absorption.

Figure 7: UV-Vis spectra. Two columns: Incident energy and normalised absorption. 

Figure 8: Powder XRD data. Single x column and multiple y columns: diffraction angle (two-theta) and intensity with increasing temperature in 50 oC intervals (30,50,100...900).
