Abstract
The crystal structures of 1-pyrrolidino-2,4-dinitrobenzene (3) and 1-morpholino-2,4-dinitrobenzene (4) were determined by single-crystal x-ray diffraction and the structures in solution were investigated by UV–visible spectrophotometry and 13C and 1H NMR spectrosccopy. Compound 4 crystallizes in the monoclinic space group P21/n with one independent molecule per asymmetric unit and 3 crystallizes in triclinic P-1 with three independent molecules per asymmetric unit. Rotation of the o-nitro group and of the amino group out of the aromatic plane was observed in both the solid state and in solution for both compounds. Copyright © 1998 John Wiley & Sons, Ltd.
