N-(Diisopropylthiophosphoryl)-N′-(R)-thioureas: synthesis, characterization, crystal structures and competitive bulk liquid membrane transport of some metal ions

Abstract	Ten N-thiophosphorylated thioureas of the common formula $RC(S)NHP(S)(OiPr)_{2}$ [R = iPrNH (1), EtNH (2), $Et_{2}N$ (3), $2,5-Me_{2}C_{6}H_{3}NH$ (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), $cyclo-C_{2}H_{2}N_{3}NH$ (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 linear, bi- or trifurcated intramolecular hydrogen bonds. Additionally, their crystal structures are stabillized by two intermolecular hydrogen bonds, which in turn lead to a centrosymmetric dimer formation. The hydrogen bonded dimers of 5–8 are packed to polymeric chains through the π⋯π stacking interactions between aryl or pyridyl rings. Competitive transport experiments involving metal ions from an aqueous source phase through a chloroform membrane into an aqueous receiving phase have been carried out using 2–6 and 8–10 as the ionophore present in the organic phase. The source phase contained equimolar concentrations of $Co^{II},$ $Ni^{II},$ $Cu^{II},$ $Zn^{II},$ $Ag^{I},$ $Cd^{II}$ and $Pb^{II}$ with the source and receiving phases being buffered at pH = 5.5 and 1.0, respectively. The obtained data were compared with the transport and extraction properties of 1 and 7, which were described recently.
