“…They were characterized by elemental and thermal analysis, IR and conductivity studies. A coupled TG-MS system was used to detection the principal volatile products of thermal decomposition and fragmentation processes for Nd(III), Pr(III) [16], Sm(III) [18], Dy(III) [19] and Tm(III) [20] compounds. Additionally, the crystal and molecular structure of La(III) [17] and Sm(III) [18] complexes were determined.…”

A novel mixed-ligand complexes of Er(III), Yb(III) and Lu(III) with title ligands were prepared and characterized by chemical and elemental analysis and IR spectroscopy, conductivity (in methanol, dimethyloformamide and dimethylsulphoxide). The thermal properties of complexes in the solid state were studied. The mode of metal-ligand coordination was discussed. The title compounds are isomorphic and isostructural in solid state. All atoms in studied compounds lie in general positions but occurrence of inversion on the midpoint of the bond linking two pyridine rings leads to existence in asymmetric unit one complex molecule and half of outer coordination sphere 4-bpy molecule. All chelating carboxylate groups are symmetrically bonded to the metal cations. The molecules of studied compounds are connected to the three dimensional network via O-HÁÁÁO and O-HÁÁÁN intermolecular hydrogen bonds. In the structures also exist C-HÁÁÁO, C-HÁÁÁCl weak hydrogen bonds and pÁÁÁÁp stacking interactions.

New complexes with formulae: Ln(4-bpy)(CBr 2-HCOO) 3 Á3H 2 O (where Ln(III) = Gd, Tb, Dy) and Er(4-bpy) 1.5 (CBr 2 HCOO) 3 Á3H 2 O, were prepared and characterized by chemical, elemental analysis and IR spectroscopy. The nature of metal-ligand coordination was studied. All of them are crystalline. Gd(III), Tb(III) and Dy(III) complexes are isostructural in one group. Conductivity studies (in methanol, dimethyloformamide and dimethylsulfoxide) were also discussed. The thermal properties of complexes in the solid state were studied using TG-DTG techniques under dynamic flowing air atmosphere. TG-MS system was used for Tb(III) (as an example of isostructural compound) and Er (III) complexes to analyze principal volatile thermal decomposition and fragmentation products evolved during pyrolysis in dynamic flowing air atmosphere.
