Ketorolac tromethamine or 1,3-dihy-droxy-2-(hy-droxy-meth-yl)propan-2-am-inium 5-benzoyl-2,3-di-hydro-1-pyrrolizine-1-carboxyl-ate, CHNO ·CHNO , was studied by single-crystal and powder X-ray diffraction methods. One cation and one anion are present in the asymmetric unit. In the crystal, N-H⋯O and O-H⋯O hy-dro-gen bonds link the cation and anion. All the hy-dro-gen-bond inter-actions result in the formation of a di-periodic layer in the (100) crystallographic plane.
通过单晶和粉末X射线衍射方法对酮咯酸氨丁三醇或1,3 - 二羟基 - 2 -(羟甲基)丙烷 - 2 - 铵5 - 苯甲酰基 - 2,3 - 二氢 - 1 - 吡咯嗪 - 1 - 羧酸盐(CHNO·CHNO)进行了研究。不对称单元中存在一个阳离子和一个阴离子。在晶体中,N - H⋯O和O - H⋯O氢键将阳离子和阴离子连接起来。所有氢键相互作用导致在(100)晶面上形成双周期层。
