(4-Nitro-phen-yl)methyl 2,3-di-hydro-1H-pyrrole-1-carboxyl-ate: crystal structure and Hirshfeld analysis.

In the title compound, C(12)H(12)N(2)O(4), the di-hydro-pyrrole ring is almost planar (r.m.s. deviation = 0.0049†à ) and is nearly coplanar with the adjacent C(2)O(2) residue [dihedral angle = 4.56†(9)°], which links to the 4-nitro-benzene substituent [dihedral angle = 4.58†(8)°]. The mol-ecule is concave, with the outer rings lying to the same side of the central C(2)O(2) residue and being inclined to each other [dihedral angle = 8.30†(7)°]. In the crystal, supra-molecular layers parallel to (10-5) are sustained by nitro-benzene-C-H⋯O(carbon-yl) and pyrrole-C-H⋯O(nitro) inter-actions. The layers are connected into a three-dimensional architecture by π(pyrrole)-π(nitro-benzene) stacking [inter-centroid separation = 3.7414†(10)†à ] and nitro-O⋯π(pyrrole) inter-actions.
