New carbacylamidophosphates (CAPh) and CAPh-containing coordination compounds: structural peculiarities

The new carbacylamidophosphate derivative HL1 (1) with general formula Cl3CC(O)N(H)P(O)(CH2C5H4N)2 named 2,2,2-trichloro-N-(3-(aminomethyl)pyridine)-1-yl-phosphoryl)-acetamide), the potassium, lanthanide and uranyl (VI) complexes with the different CAPh ligands: KL2·H2O (2) and Eu(L2)3·H2O (3) with 2,2,2-trichloro-N-(dimorpholinophosphoryl)acetamide (CCl3C(O)N(H)P(O)(N(C2H4)2O)2, HL2), Ce(L3)3(i-PrOH)2·i-PrOH (4) with N-(bis(phenylamino)phosphoryl)-2,2,2-trichloroacetamide (CCl3C(O)N(H)P(O)(NHC6H5)2, HL3), Nd(NO3)3(HL4)2 (5), Nd(NO3)3(HL5)2 (6) and UO2(NO3)2(HL5)2 (7) (HL4=CH3(C4H3N)C(O)N(H)P(O)(N(CH3)2)2 –N-(bis(dimethylamino)phosphoryl)-1-methyl-1H-pyrrole-2-carboxamide, HL5=CH3(C4H3N)C(O)N(H)P(O)(N(C2H5)2)2—N-(bis(diethylamino)phosphoryl)-1-methyl-1H-pyrrole-2-carboxamide) have been synthesized. Obtained compounds were characterized by means of FTIR, 1H and 31P NMR spectroscopy. Crystal structures of 1–7 have been determined. Compound 2 represents the first structure of the deprotonated CAPh compounds with bridging function of both carbonyl and phosphoryl groups. Structural peculiarities of CAPh ligands in the composition of the synthesized coordination compounds are discussed.
