Lanthanide Coordination Compounds with Monodentate Coordinated Β-diketone Heteroanalogue - (2,2,2-trichloro-n-(Dipiperidin-1-yl-phosphoryl)acetamide: Synthesis and Spectral Investigations

Abstract

New mononuclear six-coordinate lanthanide coordination compounds [Ln (HL)3Cl3] (HL = (2,2,2-trichloro-N-(dipiperidin-1-yl-phosphoryl)acetamideCCl3C(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, spectroscopic methods (FTIR, 1H- and 31P-NMR, UV-Vis). The structure of [Sm(HL)3Cl3] has been further confirmed by single crystal X-ray diffraction analysis.
