“…Changes observed in the IR spectra of complexes indicate that title ligands coordinate to lanthanide ions [2,4,5,16,[21][22][23]. Probably, the large electronegativity of the substitute bromide atoms in carboxylate group suggests monodentate type of coordination of this ligand.…”

In this study, new complexes with formulae: Ce(4bpy)(CHBr 2 COO) 3 ÁH 2 O, Ln(4-bpy) 0.5 (CHBr 2 COO) 3 Á2H 2 O (where Ln(III) = Pr, Nd, Sm; 4-bpy = 4,4 0-bipyridine) and Eu(4-bpy)(CHBr 2 COO) 3 Á2H 2 O were prepared, and characterized by chemical and elemental analyses, and IR spectroscopy. The way of metal-ligand coordination was discussed. They are small crystalline. The complexes of Pr(III), Nd(III), and Sm(III) are isostructural in group. Conductivity studies (in methanol, dimethylformamide, and dimethylsulfoxide) were also performed and described. The thermal properties of complexes in the solid state were studied using TG-DTG techniques under dynamic flow of air atmosphere. TG-MS system was used to analyze principal volatile thermal decomposition and fragmentation products evolved during pyrolyses of Ce(III) and Sm(III) complexes in dynamic flow of air atmosphere.

“…A survey of literature shows that crystal structures and luminescent properties on ternary lanthanide complexes (Ln= Sm, Eu, Tb, Dy, Nd, Gd, Er) containing benzoic and its derivatives and 1,10-phen or 2'2-bipy have been investigated extensively. [6][7][8][9][10][11][12][13][14][15][16][17] However thermal behaviour and non-isothermal kinetics of these complexes are rare in literatures. In material science, the investigation of thermal analysis for lanthanide aromatic carboxylic acids complexes is an important field.…”

The complex [Ho(BA) 3 bipy] 2 (BA=benzoate; bipy=2,2′-bipyridine) was synthesized and characterized by elemental analysis, infrared spectra, ultraviolet spectra, single-crystal X-ray diffraction, thermogravimetry and differential thermogravimetry (TG-DTG) techniques. The crystal is monoclinic with space group P2 1 /n. The unit cell parameters are: a=14.1114(8) Å, b=15.3743(9) Å, c=25.8887(14) Å, β=103.555(2)°. Two Ho 3+ ions are connected by four carboxylic groups through a bridging bidentate mode. The thermal decomposition behavior of the title complex under nitrogenous atmosphere was studied using the TG-DTG, and IR techniques. The non-isothermal kinetics was investigated by using the Popescu method and the integral iso-conversional non-linear method (NL-INT). The mechanism function of the first decomposition step was determined. The thermodynamic parameters (ΔG ≠ , ΔH ≠ and ΔS ≠ ) were also calculated, and kinetic parameters (activation energy E and the pre-exponential factor A) were also obtained.
