  A crystal structure determination of 2,2'-bipyrroyl (1; 2,2'-dipynyl-diketone, bis (2-pyrrolyl)ethanedione) and its spectroscopic properties in solution are reported. In the crystal, 1 self-assembles via hydrogen bonding into supramolecular ribbons that extend indefinitely through the crystal lattice. The observed molecular conformation is one where each pyrrole ring and adjacent carbonyl group are co-planar (torsion angle similar to 0.9 degrees), with the N-H pointing in the same direction as the C=O. The two carbonyls have a transoid but not co-planar geometry with a torsion angle of similar to 128 degrees. Adjacent molecules in the crystal are linked by pairs of intermolecular hydrogen bonds, pyrrole NH to carbonyl oxygen, to form a matrix of polymeric chains that lie like neatly stacked, parallel streams of ribbons. Molecular mechanics calculations on the monomer indicate an intramolecularly hydrogen bended planar conformation (sp, ap, sp) at the global energy minimum. In CHCl3, 1 is monomeric according to Vapor pressure osmometry (MWobs = 179+/-10 vs MWcalc = 188). In THF, the measured molecular weight is 340+/-15, which corresponds best to one molecule of 1 solvated by two THF molecules (MW = 322 for C10H8N2O4. 2 C4H8O) rather than to a dimer.
