Figure 3 A view of a supramolecular dimer mediated by O—H⋯O hydrogen bonds (orange dashed lines) highlighting the centrosymmetric 24-membered {⋯OC3N2C4OH}2 synthon formed between anions, and the attachment of two cations via N—H⋯O hydrogen bonding (orange dashed lines). Hydrogen atoms not participating in hydrogen bonding are omitted for clarity. Colour code: O, red; N, blue; C, grey; and H, green. |
