A fit between molecules (1)–(6), carried out using the naphthyl and imine group atoms (N1/C1–C11). The fit was calculated with the Structure Overlay command in Mercury (Macrae et al., 2008), taking as a target the first independent molecule in the first structure (1) (dark-gray molecule). For compounds (3) and (4), the refined model was inverted, in order to fit only S-C12 isomers. Note the almost perfect fit obtained for (2), (5) and (6). |
