monoethanolamine 臭化水素酸鹽의 結晶 및 分子構造가 X-線 回折法에 依하여 解明되었다. 이 結晶은 三斜軸結晶系에 속하며, 空間群은 Pi이고 單位細胞에는 두個의 化學單位가 포함되어 있다. 세포상수는 a=4.54${AA}$, b=7.45${AA}$, c=7.76${AA}$, ${alpha}=102.5^{circ}$, ${eta}=93.6^{circ}$, 및 ${gamma}=78.7^{circ}$이다. 구조해석의 결과 monoethanolamine의 臭化水素酸鹽은 鹽酸鹽과 동형결정구조임이 밝혀졌다
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, ${eta}$=93.6, ${gamma}=78.7^{circ}$. The present structure determination confirmed that the structure of monoethanolamine hydrobromide is isomorphous with that of monoethanolamine hydrochloride
