The reaction of potassium salts of N-thiocarbamoylamidophosphates RC(S)NHP(O)(OPr-i)2X [X = PhNH, p-MeOPhNH, p-BrPhNH, i-PrNH, t-BuNH, Et2N, C5H10N, OC4H8N, C6H11NH] with Zn(II) cation gives complexes of the composition Zn(L-O,S)2. The Cd(II) complexes could not be isolated under analogous conditions because of their hydrolytic lability. The reaction of thioureas (X = PhNH, p-MeOPhNH) with Cd(II) acetate in DMF provides stable solvato complexes of the composition Cd(DMF)2L2. The structure of the resulting compounds was studied by means of IR, 1H, and 31P NMR spectroscopy and EI and ESI mass spectrometry.
N-硫代氨基甲酰氨基磷酸钾盐的反应 RC(S)NHP(O)(OPr-i)2X [X = PhNH, p-MeOPhNH, p-BrPhNH, i-PrNH, t-BuNH, Et2N, C5H10N, OC4H8N, C6H11NH] 与 Zn(II) 阳离子生成组成为 Zn(L-O,S)2 的络合物。 Cd(II) 配合物由于其水解不稳定性而无法在类似条件下分离。硫脲 (X = PhNH, p-MeOPhNH) 与乙酸 Cd(II) 在 DMF 中反应,得到组成为 Cd(DMF)2L2 的稳定溶剂化配合物。通过IR、1H和31P NMR光谱以及EI和ESI质谱研究了所得化合物的结构。
