Dibenzyl 3,3′,4,4′-tetramethyl-5,5′-(ethynediyl)bis(pyrrole-2-carboxylate)
The title molecule, C30H28N2O4, has crystallographic twofold rotation symmetry, with the pyrrole planes forming a dihedral angle of 40.49 (4)°. The pyrrole N—H donor and adjacent ester carbonyl acceptor form R22(10) hydrogen-bonded rings about inversion centers, leading...
