Figure 5
(a) The rectangular-shaped ring formed by the intermolecular O11—H11⋯N1(−x + 1, −y + 1, −z + 1) and O8—H8⋯N2(x − 1, y, z) hydrogen bonds in (II). (b) The one-dimensional chain formed by the O3—H3⋯N4(x − 1, y, z − 1) and O5—H5⋯N3 hydrogen bonds in (II). H atoms not involved in the interactions have been omitted for clarity. (c) The zero-dimensional plus one-dimensional poly(pseudo)rotaxane motif in (II). H atoms have been omitted for clarity. |
