In the crystal structure, the acidic H atoms of 47phenH+ and HmtpO form strong hydrogen bonds with the water molecules, which in turn act as hydrogen-bond donors, forming links between them and towards the carbonyl O atom of HmtpO, the non-protonated N atom of 47phen+ and one of the O atoms of the anion.}, organization = {We acknowledge financial support from the Spanish Ministerio de Ciencia y Tecnología (project CTQ2008–00037/PPQ) and from the Junta de Andalucía (research group FQM 195).
