Figure 4
(a) A view of the pyrimidine–pyrimidine base pairs and π–π stacking inter­actions in (I). Hydrogen bonds are drawn as purple dotted lines and π–π interactions as blue dashed lines (one of the disordered conformations of each 2-TPC ring and some H atoms have been omitted for clarity). The symmetry codes are as given in Table 2[link] and the text. (b) A view of the π–π interactions (blue dashed lines; one of the disordered conformations of each 2-TPC ring and some H atoms have been omitted for clarity). The 2-TPC ring is sandwiched between two OMP rings. [Symmetry codes: (vii) x − 1, y − 1, z; (viii) x, y − 1, z.] (c) A view of the three-dimensional supra­molecular structure. Hydrogen bonds are drawn as light-blue dashed lines (one of the disordered conformations of each 2-TPC ring has been omitted for clarity).
