(3S)-Benzyl N-(1-hydroxy-2,5-dioxo-pyrrolidin-3-yl)carbamate: two-dimensional sheets built from O-H center dot center dot center dot O, N-H center dot center dot center dot O, C = O center dot center dot center dot C = O and C-H center dot center dot

摘要

The title compound, C10H12O5N2, crystallizes with two independent molecules in the asymmetric unit. The molecules in the crystal structure are arranged into one-dimensional substructural ribbon motifs stabilized by a combination of two O-H center dot center dot center dot O and three N-H center dot center dot center dot O intermolecular hydrogen bonds, and also augmented by short C=O center dot center dot center dot C=O carbonyl-carbonyl interactions. Two intermolecular C-H center dot center dot center dot O short contacts between adjacent ribbons generate complex two-dimensional sheets on the ab plane. Adjacent sheets are linked via C-H center dot center dot center dot pi(arene) interactions, resulting in a complex three-dimensional framework.
