2,2'-(Propane-2,2-diyl)bis(1<i>H</i>-pyrrole)

The title compound, C₁₁H₁₄N₂, crystallized with two independent molecules (<i>A</i> and <i>B</i>) in the asymmetric unit. The two molecules differ only slightly, with the pyrrole rings being inclined to one another at a dihedral angle of 87.67 (8)° in molecule <i>A</i> and 88.09 (7)° in molecule <i>B</i>. In the crystal, there are no classical hydrogen bonds, but the two pyrrole NH groups of one molecule are involved in N-H ··· π interactions with the pyrrole rings of the other molecule. In this manner, a compact box-like arrangement of the two independent molecules is formed.
