Özet

The crystal and molecular structure of the title compounds have been determined by X-ray analysis (N-(trichloroacetyl)morpholine, C6H8Cl3NO2, P2(1)/a, a = 9.869(l) Angstrom, b = 12.287(l) Angstrom, c = 16.060(l) Angstrom, beta = 98.773(7)degrees, Z = 8; 2,6-di(trichloroacetyl)cyclohexanone, C10H8Cl6O3, Pbca, a = 10.553(l) Angstrom, b = 15.405(2) Angstrom, c = 18.435(2) Angstrom, Z = 4). The morpholine and cyclohexane rings of both compounds adopt the chair conformation. There are some intra- and intermolecular hydrogen bonds in the title compounds, so the crystal structures of them are stabilized by C-H... Cl and C-H... 0 intra- and inter molecular hydrogen bonds.
