SYNTHESIS AND CRYSTAL STRUCTURE OF 4,5-DIBROMO-o-OXYLYL-17-CROWN-5
摘要:
The title compound[C16H22Br2O5] (3). was synthesized and characterized by 1H-NMR, MS and elemental analysis. Pale yellow prism crystallized from anhydrous ethanol solution was investigated by X-ray structural analysis. Crystal data:orthorhombic system, space group Pbca, Mr=454.2, a=17.664 (4) Å, b=8.625 (2) Å, c=24.269 (5) Å, z=8, Dc=1.632g/cm3, F (000) =1776. The structure was solved by direct methods and refined to final R=0.0362, Rw=0.0357 for 1029 observed reflections with F>6.0σ (F).
