Tetramethylammonium chloride (1) has been recrystallized from pyrrole (2) yielding a pyrrole–chloride complex (I) that has been crystallographically characterized. Complex I contains a chloride anion that is bound by hydrogen bonds from two pyrrole rings and a tetramethylammonium cation. The supramolecular structure is reminiscent of a honeycomb array, comprised of a pyrrole–chloride framework with cavities occupied by tetramethylammonium moities.
