Ten N-thiophosphorylated thioureas of the common formula RC(S)NHP(S)(OiPr)2 [R = iPrNH (1), EtNH (2), Et2N (3), 2,5-Me2C6H3NH (4), 4-Me2NC6H4NH (5), 2-MeO(O)CC6H4NH (6), 2-PyNH (7), 2-PyCH2NH (8), 3-PyCH2NH (9), cyclo-C2H2N3NH (10)] have been synthesized and characterized by IR, NMR spectroscopy and elemental analysis. Molecular structures of 1 and 4–8 were elucidated by X-ray diffraction revealing
十个通式为RC(S)NHP(S)(O i Pr)2 [R = i PrNH(1),EtNH(2),Et 2 N(3),2,5-Me 2的N-硫代磷酸化硫脲C 6 H 3 NH(4),4-Me 2 NC 6 H 4 NH(5),2-MeO(O)CC 6 H 4 NH(6),2-PyNH(7),2-PyCH 2 NH(8),3-PyCH 2 NH(9),合成了环-C 2 H 2 N 3 NH(10)]并通过红外光谱,核磁共振谱和元素分析对其进行了表征。X射线衍射阐明了1和4-8的分子结构,揭示了线性,双或三叉状分子内氢键。另外,它们的晶体结构被两个分子间氢键稳定,继而导致中心对称的二聚体形成。5–8的氢键二聚体通过芳基或吡啶基环之间的π⋯π堆积相互作用将其堆积到聚合物链上。竞争性的运输实验涉及从水相通过氯仿膜进入接收水相的金属离子,使用2-6和8-10作为有机相中的离子载体进行。源相包含等摩尔浓度的Co
