Thermal studies by TG and DTG on some homobinuclear dihalide-bridged iron(III) complexes of the general type [Fe(S2CNR2)2X]2(μ}-X′ 2) were carried out in air and nitrogen atmospheres. The apparent activation energies were determined by graphical methods and the TIN temperatures were calculated from the TG profiles. Finally, a possible mechanism of the decomposition is suggested on the basis of the pyrolysis and mass spectral data.
Mass spectral and thermal studies by TG and DTG of some iron(III) binuclear complexes of the general type Fe2(R2dtc)2(tds∮)X2X/′ have been carried out to determine their modes of decomposition. Fragmentation patterns are given and possible mechanisms are discussed.
Thermogravimetric and derivative thermogravimetric curves of some complexes [Ni(S2CNHR)2] (R=Me, Et, Pri, Bui, But, Bz,p-MePh,p-MeOPh,p-ClPh,p-NO2Ph) in a dynamic nitrogen atmosphere were studied to determine their modes of decomposition. All these complexes show similar TG profiles. The weight losses in the main decomposition stages indicate conversion of the nickel(II) dithiocarbamates to sulphide. Reaction orders were estimated via the shape characteristics of the corresponding derivative thermogravimetric curves and kinetic analysis of the thermogravimetric data was performed by using the Coats-Redfern and Horowitz-Metzger methods.
