Chemical reagents The chemical reagents used in the synthesis experiments include tyrosine (C9H11NO3, 99.0 wt%, Sigma-Aldrich), histidine (C6H9N3O2, 99.0 wt%, Fluka), ciprofloxacin HCl(C17H18FN3O3 ⋅ HCl ⋅ H2O, Merck), n-hexane (C6H14, 97.0 wt%, Honeywell) and distilled water. All chemicals were used without further purification. Sample preparation and data collection Single crystals of ciprofloxacin hydrochloride were obtained through vapour diffusion of EtOH/MeCN. These crystals were then directly suspended by …
