通过对一例蒙皂石-乙二醇有机复合体的结构研究,修正了传统的结构模型,并从化学键、有机分子构型及层间域的有效空间等方面综合考虑,证明了所提出的新结构模型的合理性。在新的结构模型中,乙二醇分子为梯形排列,单位晶胞所容纳的乙二醇分子为4个,每个乙二醇分子可与硅酸盐层基底氧形成两个氢键,并且乙二醇分子的构型显示了极性分子的性质,层间域Ca离子和剩余水分子正对于六方网环的中心,与另一侧的乙二醇分子相对应,新结构模型的可信度因子R=0.081。
Through the structural study of a smectite-ethylene glycol organic complex, the traditional structural model was revised and the new chemical bonds, organic molecular configurations and the effective space of the interlayer domains were considered. It was proved that the proposed new The rationality of the structural model. In the new structural model, the ethylene glycol molecules are trapezoidal, the unit cell contains four ethylene glycol molecules, each ethylene glycol molecule can form two hydrogen bonds with the silicate base oxygen, and The configuration of the glycol molecule shows the nature of the polar molecule. The intercalation domain Ca ions and the remaining water molecules are right in the center of the hexagonal network and correspond to the glycol molecules on the other side. The new structural model is plausible Degree factor R = 0.081.
