A novel mixed-ligand complexes with empirical formulae: Ln(4-bpy)(CCl2HCOO)3.H2O (where:Ln =Y, Ce,Nd, Pr andEu, 4-bpy = 4,4'-bipyridine) were prepared and characterized by chemical and elemental analysis, IR spectroscopy and conductivity measurements (in methanol, dimethylformamide and dimethylsulfoxide). Analysis of the powder diffraction patterns showed that the obtained complexes are crystalline and isostructural compounds. 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: Ln2O3 (Y, Nd, Eu), Pr6O11 and CeO2. A coupled TG-MS system was used to analyse principal volatile thermal decomposition (or fragmentation) products evolved during pyrolysis of Pr(III) and Nd(III) complexes. In air major profiles for ion currents are observed with m/z = 12, 18, 29, 30, 35, 36, 44, 47 amongst others.
