“…The complexes prepared with Schiff bases thermally release the solvent molecules (DMF) in their structures. This phenomenon is clearly seen in the thermogravimetric analysis [52]. After releasing the coordinative solvent molecules, there remain NiL and halide salts behind.…”

Mono-, di-and trinuclear complexes of Fe(III), Co(II), Ni(II), and Cu(II) ions with Bis-N,N'(salicylidene)-1,3-diaminopropane (LH2), Bis-N,N'(salicylidene)-2,2'-dimethyl-1,3diaminopropane (LDMH2), N(salicylidene)-2-hydroxyaniline (SAP), and Tris-N,N',N''(salicylidene)-2,2',2''-aminoethylamine (Trensal) were prepared and ionized with 30-110 eV electrons in direct inlet (DI). Compounds with metal-oxygen covalent bonds were observed to give molecular peaks, whereas polynuclear complexes containing coordinative bonds did not have such peaks. It was concluded that the coordinative bonds were dissociated by electron impact (EI). The thermogravimetric analysis reveals that the molecular peak observed for the mononuclear complexes which are stable up to 300 °C is also the base peak. The peaks obtained for the di-and trinuclear complexes that decomposed at these temperatures could not be observed as a molecular signal. The resulting fragments were evaluated and compared with the literature data.
