title: (4S,5S)-2-(2-Bromo-phen-yl)-1,3-dioxolane-4,5-dicarboxamide.
abstract: The asymmetric unit of the title compound, C(11)H(11)BrN(2)O(4), contains two crystallographically independent mol-ecules in which the bromo-phenyl rings are oriented at dihedral angles of 39.28 (3)°. The dioxolane rings adopt envelope conformations. Intra-molecular N-H⋯O hydrogen bonds result in the formation of four five-membered rings, having planar and envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into chains along the b axis, forming R(2) (2)(8) ring motifs.
