Figure 5
Supramolecular features within the crystal structure of (2) comprise π–π contacts and mutual N1⋯I1ⁱⁱ and N1ⁱⁱ⋯I1 interactions. Moreover, there are non-conventional hydrogen bonds I1ⁱⁱ⋯H6, I1⋯H6ⁱⁱ, and H10B⋯N2ⁱⁱⁱ. Intermolecular contacts are shown as dashed lines. Only atoms H6, H6ⁱⁱ, and H10B which are involved in hydrogen bonding (black dashed lines) are shown as green spheres of an arbitrary radius. Purple dashed lines connect centroids of π–π associated dimers.
