Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) experiments were carried out on the [TBuA][M(dca)3] and [TPnA][M(dca)3] samples. On subsequent data analysis, values for Tm, the enthalpy of fusion (ΔHf), the entropy of fusion (ΔSf) and the temperature of decomposition (Td), were identified (Fig. , Table ). A decreasing trend in Tm values with the increasing number of carbons in A site chains is evident, i.e.
