Abstract
[CrFe2O(AcO)6(TEP)3]Cl, (1), and [CrFe2O(AcO)6(TMP)3]Cl, (2), were prepared by replacing 3 water molecules in the [CrFe2O(AcO)6(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.
