1-(Morpholin-4-ylmethyl)pyrrolidine-2,5-dione

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.003 Å; R factor = 0.033; wR factor = 0.089; data-to-parameter ratio = 13.6.In the title compound, C 9 H 14 N 2 O 3 , the morpholine ring adopts the usual chair conformation. The pyrrolidine-2,5-dione ring adopts an extremely flattened envelope conformation. The crystal structure is stabilized by weak C-HÁ Á ÁO interactions.
