Specific Features of the Structure of Chelate Complexes of <Emphasis Type="Italic">N</Emphasis>-Thiocarbamoylamidophosphates with Zn(II) and Cd(II) Cations

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.
