“…So the results of classification of isomeric salts by modifications of the CT with position of the carboxylate groups practically overlap the subgroups obtained in considerations of the ligand structure. The luminescence spectra of the europium salts of PDA isomers could be divided into the same subgroups [11,17].…”

“…This work is a continuation of our studies on spectroscopy of the lanthanide pyridinedicarboxylates and pyridinecarboxylates [11,12]. As it follows from analysis of pyridinecarboxylates, being a simpler system than salts of PDA, the coordination function of the carboxylate groups is monodentate in picolinate, bidentate-cyclic or bidentate-bridging in nicotinates and bidentate-cyclic in isonicotinates.…”

“…Wasylina et al [28] and Harmon and Shaw [15] have reported the IR spectrum of only one polymorphic form of CA and have given partial vibrational assignments. Several metal complexes of CA have been characterised by IR [7,[29][30][31][32] and Raman [33] spectroscopies. As can be easily seen from Figures 6 and 7, the two polymorphs show significant differences in both IR and Raman spectra for either the presence of some bands only for one polymorph or the wavenumber positions of many bands or their relative intensities.…”

“…Outros tipos de complexos de alumí-nio(III) 31 , manganês(I) 32 , európio 33,34 e térbio 34 , envolvendo este mesmo ligante, têm sido preparados com diferentes finalidades. O ácido quinolínico pode também ser usado como material de partida na preparação de outras classes de substâncias 35 .…”
