The physicochemical properties of a new organic cyclohexaphosphate, [5-Cl-2,4-(OCH3)2C6H2-NH3]6P6O18·4H2O, are discussed on the basis of an X-ray crystal structure investigation. This compound crystallizes in the monoclinic space group C2/c, with cell parameters a = 37.987(7) Å, b = 13.125(4) Å, c = 14.331(5) Å, β = 98.21(3)°, Z = 4, V = 7072(3) Å3. Its crystal structure is determined and refined to
在 X 射线晶体结构研究的基础上讨论了一种新的有机环六磷酸盐 [5-Cl-2,4-(OCH3)2C6H2-NH3]6P6O18·4H2O 的物理化学性质。该化合物在单斜空间群 C2/c 中结晶,晶胞参数 a = 37.987(7) Å, b = 13.125(4) Å, c = 14.331(5) Å, β = 98.21(3)°, Z = 4 , V = 7072(3) Å3。对于 5223 次独立反射,它的晶体结构被确定并精炼为最终的 R = 0.058。原子排列可以描述为由 P6O18 环阴离子和水分子构成的层状组织。在这些层之间,有机基团位于与 P6O18 环的氧原子和水分子形成氢键的位置。两个相邻有机阳离子环之间的分子间 π-π 堆积相互作用有助于建立晶体堆积。固体 31P MAS-NMR 光谱与 X 射线结构一致。从头算计算允许将三个磷信号归因于独立的晶体学位点。该化合物的特征
