After the release of water, a complex degradation
process of the remaining material is observed. As shown inFig. 5,
two consecutive TG steps are observed: the first one between
216 and 473C (with two weak exothermic peaks located at 270
and 458C in DTA) and the second one between 473 and 565C.
For the last step, a very strong exothermic peak located at 528C
is observed in the DTA curve. These peaks are attributed to the
combustion of the organic ligand to produce Mn3O4as final product. This substance was identified by PXRD measurements (See
Fig. S1). The mass loss observed at 565C was 84.75% and it was
