13.32% corresponds to the percentage (calcd.13.44%) of the Co
and O components, indicating that the final product is 0.5Co2O3.

middle endothermic peak at 302.2◦C, and one strong exothermic
peak at 479.8◦C on the DSC curve of compound 1.
As canbeseenfromFigure6, therearetwoweakendothermic
peaks at 198.9◦C and 312.1◦C, and one strong exothermic peak
at 443.9◦C on the DSC curve of complex 2. The first weight loss
of 5.69% (calcd. 5.83%) occurs from 142.0◦C to 224.0◦C, which
is attributed to the loss of coordinated water molecules. The
second weight loss of 36.71% (calcd. 36.28%) between 224.0◦C
and 354.0◦C corresponds to the loss of two -COOH and two
COO– and two -OCH3. The third weight loss of 44.28% (calcd.
44.38%) ranges from 354.0◦C to 607.0◦C corresponding to the
loss of the remaining organic ligand. The remaining weight of
