Four iron(III) complexes [Fe(2‐OH‐phenone) 3 ] ( 1 – 4 ), in which 2‐OH‐phenone is the anion of the ligands 2‐OH‐acetophenone(Hapo) ( 1′ ), 2‐OH‐propiophenone(Hppo) ( 2′ ), 2‐OH‐benzophenone(Hbpo) ( 3′ ) and 2‐OH, 4‐OCH 3 ‐benzophenone(Hopo) ( 4′ ), were synthesized and characterized by physicochemical and spectral (IR, UV/Vis, Mössbauer) data. The X‐ray diffraction study of compound 2 , tris(2‐hydroxypropiophenone)iron(III) [Fe(ppo) 3 ] revealed a facial octahedral arrangement of the ligands around the iron(III) atom. The thermal decomposition for the compounds 2 and 4 was studied in nitrogen atmosphere, from ambient temperature to 1000 °C, by using the TG/DTG‐DTA technique. The compounds are very stable at ambient temperature but unstable upon heating giving as residue carbonaceous iron oxide.
