A low-resolution X-ray molecular structure of the title hydrated salt, [Na(C19H21N6O6)]·2H2O, displays scorpionate character and resolves apparent ambiguities between solution and solid-state NMR spectroscopies. The (13)C NMR CPMAS spectrum is consistent with this structure showing some splittings, which have been rationalized using GIAO/B3LYP/6-311++G(d,p) theoretical calculations.
标题水合盐[Na(C₁₉H₂₁N₆O₆)]·2H₂O的低分辨率X射线分子结构显示出螯合特性,并解决了溶液核磁共振光谱和固态核磁共振光谱之间明显的模糊性。¹³C核磁共振交叉极化/魔角旋转(CPMAS)光谱与该结构一致,显示出一些分裂,这些分裂已通过GIAO/B3LYP/6-311++G(d,p)理论计算得到合理解释。
