Figure 2
A packing view of (I), along the [110] direction, showing on a grey background the two independent chains running top to bottom, parallel to [10], and on a white background their c-glide symmetry-related images, perpendicular to the plane of the figure (one of these strips has been isolated on a dark triangular background). N—H⋯N and C—H⋯N interactions are represented by dashed lines and C—H⋯π interactions are represented by thin double lines. Molecules drawn with thin lines correspond to molecule 1 and those in bold to molecule 2. Cg centroids (with underlined labels) are above or below the projection plane.
