title: Two 2,2-dihalo-N-(1-phenylethyl)cyclopropane-1-carboxamides.
abstract: The crystal structures of (1R,1'S)-2',2'-dichloro-N-(1-phenylethyl)cyclopropane-1'-carboxamide, C(12)H(13)Cl(2)NO, (I), and (1R,1'R)-2',2'-difluoro-N-(1-phenylethyl)cyclopropane-1'-carboxamide, C(12)H(13)F(2)NO, (II), have been determined. Both crystals contain two independent molecules with different conformations of the phenylethyl groups. In the crystals of both compounds, the molecules are linked together by N-H...O hydrogen bonds, thus forming chains in the a direction.
