Thermal decomposition of complexes - Manganese(II) and vanadyl with cis- and iron(II), manganese(II) and vanadyl with trans-n,n'-bis(salicylidene)-1,2-cyclohexanediamine (salcn)

The iron(II) complex of the Schiff bases trans-N,N'-bis(salicylidene)-1,2-cyclohexanediamine (Salen), manganese(II) and vanadyl complexes of the Schiff bases cis- and trans-N,N'-bis(salicylidene)-1, 2-cyclohexanediamine (Salen) were prepared and characterized by IR spectroscopy, and elemental analysis. These new complexes were submitted to thermal analysis (TG and DSC) under dynamic air atmosphere. The differences in the decomposition profiles were related to the structure of isomers and decomposition intermediates were characterized according to their X-ray diffraction pattern and by their infrared spectrum.
