Figure 4
Section of the crystal structure of 1, showing π–π stacking between the 6-methoxy-5-methylpyrimidin-4-yl moiety and the benzimidazole system in adjacent molecules. The distance between the centroids of the two six-membered rings (thin dashed line) is 3.6164 (11) Å. Thick dashed lines represent hydrogen bonds. Carbon-bound H atoms have been omitted for clarity. Symmetry code: (i) −x + 1, −y + 1, −z. |
