摘要

The compound C_(15)H_(18)NO_2Br was synthesized and characterized by X-ray diffraction. The crystals belong to the monoclinic system, sp. gr. P2_1, a = 8.913(2) ?, b = 23.637(6) ?, c = 13.892(3) ?, β = 90.31(2)°, Z = 8, V = 2926.8(12) ?~3, ρ_(calc) = 1.472 g/cm~3. The bond lengths and bond angles in two molecules are equal within an experimental error and are typical of this class of compounds. The conformational differences of the saturated heterocyclic and methoxycarbonyl fragments of the molecules result in the presence of two crystallographically independent molecules in the crystal structure.
