Notes:
The structures of the potential non-linear optical (NLO) materials N-[2-(isopropylamino)-5-nitrophenyl]acetamide, (I) C11H15N3O3, and N-[2-(butylamino)-5-nitrophenyl]acetamide, (II) C12H17N3O3, have been investigated by X-ray analysis. To compare them with the structure of N-[2-(dimethylamino)-5-nitrophenyl]acetamide, (III) C10H13N3O3, a known NLO compound, we had to redetermine the structure of (III), since it was described only briefly in the literature. There are two molecules in the asymmetric unit of compound (I), which have different orientations of the substituents with respect to the benzene ring. The packing of molecules in (II) and (III) contains stacks but both (I) and (II) crystallize in a centrosymmetric space group, which renders them inappropriate for NLO applications.
