Artykuł
Luminescence, excitation of luminescence, IR and Raman spectra of a variety of carboxylates Eu(RCOO)3.Phen (Phen–1,10-phenanthroline) consisting of acetate, propionate, lactate, capronate compounds, and Eu(CH3COO)3.Ph (Ph–six 1,10-phenanthroline derivatives) were examined. Crystal field parameters for model compounds were calculated. The crystal structure of the europium acetate Eu(CH3COO)3.Phen was solved by X-ray method. Dependence of the spectroscopic characteristics on variation of both types of ligands, indicating details of the structure of compounds, was examined. Reciprocal influence of inequivalent ligands in europium carboxylates was analysed. It was demonstrated that steric factors are as significant as the donor–acceptor properties of the ligands in creation of the structure of compounds under investigation.
