(3) Harris, S. Polyhedron 1989, 8, 2843-2882. a black powder, sparingly soluble in xylene, was also obtained as a byproduct, and in the latter case, the black powder was identified as the known cubane cluster (i7-C5H5) 4Fe4S4 by mass and NMR spectroscopy. 4 This reaction is in sharp contrast to the reaction of (77-C5H5) Co (CO) 2 with S8 and PhC^ CPh under similar conditions, which gives themononuclear dithiolene complex (-C5H5) Co (S2C2Ph2). 5 Compounds 2a and 2b were characterized by the usual spec-troscopic methods. 6 The FAB mass spectra of 2a and 2b show molecular ion peaks centered at m/z= 1106 and 966, respectively. The NMR spectrum of 2a (200 MHz) in Cl> Cl3 exhibits a methyl singlet (i)-C5Me5) at 1.48 ppm and two Pi multiplets at 7.2-7.3 and 7.4-7.5 ppm. Similarly, the spectrum of 2b shows
