ADDITION OF METHYLENE GROUPS TO FE3(CO)9(MU-3-TE)2

At room temperature, Fe3(CO)9(mu-Te)2 reacts with diazomethane to form (CO)6Fe2(mu-TeCH2Te) (I) and (CO)6Fe2Te2(CH2)2 (II). Complexes I and II have been separated by chromatography and characterised by IR and NMR spectroscopy, mass spectrometry and microanalysis. Complex I was also subjected to an X-ray diffraction study. The crystals are monoclinic, space group P2(1)/c with a = 6.864(2), b = 13.926(3), c = 14.159(3) angstrom, beta = 104.43(2)-degrees, V = 1310.6(5) angstrom, Z = 4, D(c) = 2.79 g cm-3 and R = 0.043
