The first crystal of nitrosyl pyrrole with interesting packing

What is it about?

We report the first crystal structure of a nitrosyl pyrrole. Interestingly, the cooperative hydrogen bonds in this NO-substituted pyrrole lead to a trimeric structure with bifurcated halogen bonds at the ends, forming a two-dimensional (2D) layer with interstitial voids having a radius of 5 A ˚ similar to some reported macrocyclic porphyrins, these layers are held together by pi-pi interactions.

Why is it important?

It is the first crystal of a nitrosyl pyrrole and it can be relevant because the N and O of the nitrosyl group are pointing inward to a center, forming an interesting motif that is expanded in 2D by Br---Br halogen interactions, leading a structure with interstitial voids. This is very important in crystal engineering and nano-structure materials.
