i) an XRPD pattern having peaks at 10.1, 13.3, 24.5, 26.7 and 28.5 degrees-2-theta±0.2 degrees 2-theta;
ii) an XRPD pattern as depicted in FIG. 6 or FIG. 8;
iii) a solid state 13C-NMR spectrum with peaks at 165.9, 162.0, 131.6, 128.9 and 103.7 ppm±0.2 ppm;
iv) a solid state 13C-NMR spectrum following chemical shift absolute differences from a peak at 65.3 ppm±2 ppm of 100.6, 96.7, 66.3, 63.6 and 38.4 ppm±0.1 ppm;
v) a solid state 13C NMR spectrum having chemical shift difference from a peak at 165.9 ppm±1 ppm of 100.6 ppm±0.1 ppm;
vi) a solid state 13C-NMR spectrum substantially as depicted in FIG. 10; or
combinations of (i)-(vi).
