Abstract :[CrFe2Oinsert ignore into journalissuearticles values(AcO);6insert ignore into journalissuearticles values(TEP);3]Cl, insert ignore into journalissuearticles values(1);, and [CrFe2Oinsert ignore into journalissuearticles values(AcO);6insert ignore into journalissuearticles values(TMP);3]Cl, insert ignore into journalissuearticles values(2);, were prepared by replacing 3 water molecules in the [CrFe2Oinsert ignore into journalissuearticles values(AcO);6insert ignore into journalissuearticles values(H2O);3]Cl complex with triethyl- and trimethyl-phosphates, respectively. FT-IR spectroscopy confirmed an oxo-centered, carboxylate-bridged, heteronuclear triangular structure for the title compounds. M3O and MO4 units adopted D3h and D4h local symmetry, respectively, and are surrounded by 6 bridging acetates with C2v local symmetry.
