This article outlines alkali-, thallium (I) and onic-salts of dimethyl- N-trichloracetylamidophosphate [HL]. A brief description of the syntheses and IR and NMR spectroscopic studies of seven carbacylphosphortriamide compounds are given. All synthesized compounds have been structurally characterized. It was determined that the type of metal–ligand interaction in Na[L], Rb[L] and Tl[L] was ionic. IR spectroscopic and X-ray structure analysis of the [SbPh 4L] complex determined the preferable donor center (phosphoryl oxygen atom in the L −). Alkali-, thallium (I) and onic-salts of dimethyl- N-trichloracetylamidophosphate [HL] were synthesized from non-aqueous solutions and characterized by means of X-ray diffraction, IR and 1H NMR spectroscopy. An ionic type of metal–ligand interaction was determined in Na[L] ( 1), Rb[L] ( 2) and Tl[L] ( 3). Several compounds containing the tetraphenylphosphonium cation, such as PPh 4[L] ( 4), (PPh 4) 2[L]Br · H 2O ( 5) and (PPh 4) 2[Na 4L 6] ( 6), were obtained by an exchange reaction between PPh 4Br and ( 1) in different molar ratios. Compound 6 may be considered as the first example of an anionic complex of an alkali element in the coordination chemistry of carbacylamidophosphates. Synthesis and investigation of [SbPh 4L] ( 7) allowed the determination of the preferable donor center of the L − ligand (the oxygen atom of the phosphoryl group).
