Rezumat

14 new mononuclear six-coordinate lanthanide coordination compounds of general formula [Ln(HL)3Cl3] (Ln = La-Nd, Sm-Lu; HL = (2,2,2-trichloro-N-(dipiperidin-1-yl-phosphoryl)acetamide CCl3C(O)N(H)P(O)[N(CH2)5]2, carbacylamidophosphate (CAPh) type ligand) have been synthesized from non-aqueous solutions. The complexes have been characterized by elemental analysis, FTIR, 1H- and 31P-NMR, and UV-Vis spectroscopy. The structure of [Sm(HL)3Cl3] (1) has been further confirmed by single crystal X-ray diffraction analysis. Crystal data: trigonal, R3, with a = 24.098 Å, c = 18.025 Å, V = 9065.0 Å3, Z = 6, R1 = 0.0327, and wR2 = 0.0404. The crystal structure was solved as two crystallographically independent fragments Sm(HL)Cl: A and B that exist in the crystalline lattice due to the differences in some geometrical parameters.
