• -CD [29]. This was an indication that the structure should be quite different from hydrated β-CD. However, no guest could be located during the refinement and the present structure (henceforth “β-CD–D-NAcTrp”) was refined as a β-CD–water complex (Table 2). “β-CD–D-NAcTrp” exhibits the “herringbone
