Abstract
Transmetallation of the Fe3(μ3-X)2(CO)9 clusters (X = S, Se, or Te) under the action of (π-C8H12)PtCl2 afforded new heterometallic clusters (π-C8H12)Pt(μ3-X)2Fe2(CO)6 (2 - 4, respectively), which were characterized by X-ray diffraction analysis. The (π-C8H12)Pt fragment in these clusters is bound to two μ3-bridging chalcogen atoms X. The iron atoms are linked to each other. The coordination environment about the Pt atom is planar-square; the Pt…Fe distance is larger than 3.2 Å. In the synthesis of cluster 4, a new Pt complex was also obtained for which the structure (CO)2Pt(μ-Te)2Pt(CO)2 (5) was proposed. According to the results of differential scanning calorimetry, thermal decomposition of complex 5 gave rise only to PtTe, whereas complexes 1 - 4 gave products with the empirical formula Fe2PtX2C2O2. The influence of the steric effects on the geometry of the clusters is discussed.
