摘要：
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 nu(asym) (M2M'O) vibrations in the infrared spectra.
