  1. [a]The unit cell parameters of α-, β- and γ-VMN are taken from the SCXRD data, whilst those of δ- and ε-VMN were refined against the PXRD data. The values for δ-VMN are the data used for the structure refinement (1.4 Å), whilst the values in parentheses are the data used during simulated annealing for the structure solution (2 Å).
  2. [b]Year and method of discovery: SC, solution crystallization; MC, melt crystallization.
  3. [c]Method used for structure elucidation: SCXRD, single-crystal X-ray diffraction; 3D ED, 3D electron diffraction.
  4. [d]Sample type used for structure elucidation: SC, single crystal; CS, compact spherulite.
  5. [e]NA, not available.
  6. [f]RMSD15 values are calculated between the experimental structure and the density functional theory (DFT) energy minimized structures using Mercury software.
