16. 2 (data/ restraints/parameters: 4369/336/391), converging to R1 = 0.113, wR2 = 0.280 (on 2588, I > 2σ(I) observed data); R1 = 0.197, wR2 = 0.356 (all data). The solvate molecules were highly disordered.
17. 2 (data/restraints/parameters: 8624/64/846), converging to R1 = 0.045, wR2 = 112 (on 6260, I > 2σ(I) observed data); R1 = 0.087, wR2 = 0.151 (all data). Porphyrin crystals tend to loose crystallinity upon removal from the mother liquor at room temperature.

19. In all the structures, the O-O distances (hydrogen bonded OH-OH groups) were 2.55-2.8 Å, which indicates strong, directional hydrogen bonding interactions.
