The crystal structure of crystalline hydrates of dimethylaminoarglabine hydrochloride and dimethylaminoarglabine hydronitrate is determined by single crystal X-ray diffraction. It is established that in a crystal, water breaks the hydrogen bond between the anion and the cation in dimethylaminoarglabin hydrochloride and weakens it in dimethylaminoarglabin hydronitrate, which improves the solubility of salts in water.

水合水对二甲基氨基炔雌醇盐酸盐和硝酸盐中氢键形成的影响

二甲氨基精氨酸盐酸盐和二甲氨基精氨酸氢硝酸盐的结晶水合物的晶体结构是通过单晶X射线衍射确定的。已确定，在晶体中，水会破坏二甲氨基阿格拉宾盐酸盐中阴离子和阳离子之间的氢键，并削弱二甲氨基阿格拉宾氢硝酸盐中的氢键，从而提高盐在水中的溶解度。
