| Popis: | Two new heterotrinuclear p-chlorobenzoates, [Fe2CrO(C7H4O2Cl)6(py)3]NO3 (1) and [Cr2FeO(C7H4O2Cl)6(py)3]NO3 (2) were prepared as nitrate salts and characterized by elemental analyses (CHN), spectroscopic (infrared, electronic) studies and atomic absorption spectroscopy. These complexes are a new type of oxo-bridged mixed-metal complex in which the carboxylate ligand is p-chlorobenzoic acid. Bridging coordination modes for the carboxylates were indicated by the presence of νasym (M2M'O) vibrations in the infrared spectra. |
