ABSTRACT
The title compound, C22H33N3O4, crystallizes in the triclinic space group P with two mol-ecules in a unit cell. The two pyrrole rings are essentially planar (r.m.s. deviation = 0.002â Å) and they form a dihedral angle of 81.24â (10)° with each other. The crystal packing is stabilized by C-Hâ¯π inter-actions and π-π stacking inter-actions, forming a three-dimensional network. The Hirshfeld surface analysis and two-dimensional fingerprint plots reveal that the most important contributions for the crystal packing are from Hâ¯H (74.3%), Câ¯H/Hâ¯C (11.5%) and Oâ¯H/Hâ¯O (9.1%) contacts.
