摘要：
In the title compound, C21H28Cl2N3O6, the nitronyl nitroxide ring displays a half-chair conformation, whereas the pyrrolidine ring has an envelope conformation. These two rings are twisted to each other with N-C-C-N torsion angles around the connecting C-C bond of 48.9 (6) and -127.0 (5)degrees. The benzene ring is nearly perpendicular to the pyrrolidine ring, with torsion angles around the connecting C-C bond of 86.3 (6) and -97.7 (6)degrees. The crystal structure is stabilized by C-H...O and C-H...pi hydrogen bonds, which build up a three-dimensional network.
