Views of the three-dimensional network which makes up the structure of (IV). C—H⋯π and C—H⋯N interactions are shown as thin lines and H atoms not involved in these interactions have been omitted. (a) The two-dimensional sheet lying in the (100) plane, formed by the combination of both π-stacking and C—H⋯π interactions and C—H⋯N hydrogen bonds. (b) Two adjacent sheets, showing the π-stacking which connects them into a three-dimensional network. |
