“…This work is a continuation of our previous studies on synthesis, properties, and thermal decomposition of metal complexes with bipyridine isomers and carboxylates [1][2][3][4][5][6][7]. Lanthanide compounds are curious for many research workers in last years because of their variety applications [8][9][10][11][12][13].…”

A novel mixed-ligand complexes with empirical formulae: Ln(4-bpy) 1.5 (CCl 3 COO) 3 ÁnH 2 O (where Ln(III) = Pr, Sm, Eu, Gd, Tb; n = 1 for Pr, Sm, Eu and n = 3 for Gd, Tb; 4-bpy = 4,4 0-bipyridine) were prepared and characterized by chemical, elemental analysis and IR spectroscopy. Conductivity studies (in methanol, dimethylformamide and dimethylsulfoxide) were also described. All complexes are crystalline. The way of metal-ligand coordination was discussed. The thermal properties of complexes in the solid state were studied under non-isothermal conditions in air atmosphere. During heating the complexes decompose via intermediate products to the oxides: Pr 6 O 11 , Ln 2 O 3 (for Sm, Eu, Gd) and Tb 4 O 7. TG-MS system was used to analyze principal volatile thermal decomposition and fragmentation products evolved during pyrolysis of Pr(III) and Sm(III) compounds in air.

Crystal Structure, Spectroscopic and Magnetic Properties of a New Iron(iii) Complex

We report herein the synthesis and physicochemical characterization of a new mixed-ligand iron(III) complex of the formula (This compound is prepared by slow evaporation at room temperature and characterized by single crystal X-ray diffraction. It is characterized by IR and UV-VIS spectra and thermal analysis (TG and DTA). In this compound, the iron ion has a slightly distorted square bipyramidal environment, coordinated by two chelating oxalate ions and two water molecules. Structural cohesion is essentially established by π-π interactions between the rings of pyridine groups and intermolecular hydrogen bonds connecting the ionic entities and uncoordinated water molecules. Magnetic susceptibility measurements exhibit the paramagnetic behavior at high temperatures. However, at low temperatures, the magnetic data show the occurrence of weak antiferromagnetic intermolecular interactions between the local spins.
