A major interest at the moment is in the development of organometallic
or inorganic compound for preparation of nanoparticles.
Using of the novel compound can be useful and open a new
way for preparing nanomaterials to control nanocrystal size, shape
and distribution size. Recently, the synthesis of metal oxide nanoparticles
via thermal decomposition of novel precursor has been
reported [22–27]. Metal carboxylates are good precursors to obtain
pure metal oxides. Ahmad et al. [28] have prepared manganese
oxalate by the reverse-micellar method using cetyltrimethylammonium
bromide as the surfactant. These manganese oxalates
when decomposed in air at 450 C for 6 h led to the formation of
a-Mn2O3 about 45 nm.
