2,2'-(Propane-2,2-di-yl)bis-(1H-pyrrole)

The title compound, C(11)H(14)N(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ only slightly, with the pyrrole rings being inclined to one another at a dihedral angle of 87.67 (8)° in mol-ecule A and 88.09 (7)° in mol-ecule B. In the crystal, there are no classical hydrogen bonds, but the two pyrrole NH groups of one mol-ecule are involved in N-H(midline ellipsis)? inter-actions with the pyrrole rings of the other mol-ecule. In this manner, a compact box-like arrangement of the two independent mol-ecules is formed.
