摘要

Two series of the lanthanide (Eu, Pr) compounds ofthe formulae Ln(HX)_3C1_3 (1); Ln(HX)_3(N03)_3 (2) (whereHX=CCl_3CO-NH-PO(NEt_2)_2) with C.N. =6 and 9 wereobtained in the form of monocrystals. The spectroscopic propertiesof these compounds were investigated at 293, 77 and 4.2 K andthe results related to their structures. Correlation was made withthe spectroscopic data and structure of the Eu and Nd respectivechelates. Essential differences were found in coordination mode ofligand molecules in those systems. Intensity analysis of electronictransitions, electron-phonon coupling, as well as splitting andenergies of electronic levels were used as tests of metal bonding inthe systems under investigation. The electronic f-f transitions ofpraseodymium (1, 2) compounds show drastic differences inoscillator strength values, pointing thus at substantial differencesin symmetry of the metal centre. Judd-Ofelt parameters werecalculated with low errors of estimation. The relatively strongvibronic lines appear at displacement frequencies, correspondingto both ligand and Ln-L_n localised vibrational modes.
