Figure 4
(a) Fragment of the structure of I showing a column of molecules, down the a-axis in the crystal, sustained by π–π interactions and weak CH⋯π and CH⋯O bonds. (b) Projection of the structure nearly down the a-axis showing weak CH⋯O bonds between the columns (which are orthogonal to the drawing plane). Light-blue lines indicate the π–π interactions.
