Monoethanolamine Hydrobromide의 結晶 構造

The crystal and molecular structure of monoethanolamine hydrobromide, HOCH2CH2NH2 HBr, has been determined by X-ray diffraction methods. The crystals are triclinic, space group Pi and unit cell contains two formula units and has dimensions a = 4.54, b = 7.45, c = 7.76${\AA}$ and ${\alpha}$ = 102.5, ${\beta}$=93.6, ${\gamma}=78.7^{\circ}$. The present structure determination confirmed that the structure of monoethanolamine hydrobromide is isomorphous with that of monoethanolamine hydrochloride.
