| Abstract: | Thermal transformations of FeIII maleate, [Fe3O(OOCCH=CHCOOH)6]OH·3H2O (1), in an autogenerated atmosphere and the change in the short-range surrounding of Fe atoms during thermolysis were studied. The thermal transformations of1 are accompanied by the following processes: dehydration with simultaneous rearrangement of the ligand environment and formation of maleic acid, and polymerization of the rearranged monomer and its decarboxylation at high temperatures. In the initial stage of decarboxylation, the destruction of the metal-carboxylate Fe3O complex occurs followed by the formation of the Fe−Fe bond (r=0.246 nm). The oxidation of the Fe atoms is observed when the thermolysis duration increases. For Part 49, seeIzv. Akad. Nauk, Ser. Khim., 1998; 1145 [Russ. Chem. Bull., 1998,47, 1113 (Engl. Transl.)].
