Abstract

In the racemic crystals of (1S,2R)- or (1A,2S)-l-[N-(chloroacetyl)carbamoylamino]-2,3-dihydro-1H-inden-2-yl chloroacetate, C14H14Cl2N2O4, (I), the enantiomeric molecules form a dimeric structure via the N-H⋯O cyclic hydrogen bond of the carbamoyl moieties. In the chiral crystals of (-)-(1S,2R)-l-[N-(chloroacetyl)carbamoyIarnino]-2,3-dihydro1N-inden-2-yl chloroacetate, C14H14Cl2N2O4, (II), the N-H⋯O intermolecular hydrogen bond forms a zigzag chain around the twofold screw axis. The melting points and calculated densities of (I) and (II) are 446 and 396 K, and 1.481 and 1.445 Mg m-3, respectively.
