The reaction of Cp(2)#Co-2(CO)(2) 1 (Cp# = Cp* or Cp(x); Cp* = C(5)Me(5): a; Cp(x) = C(5)Me(4)Et: b) with equimolar amounts of As4S, (n = 3, 4) and As2S3 was investigated at different temperatures. The formation of Cp(2)(#)Co2(CO)As2S2 3, Cp(2)(#)Co(2)As(2)S(3) 4, Cp(3)(#)Co(3)As(2)S(4) 5, and Cp(3)(#)Co(3)As(4)S(2) 6 was observed in ratios depending on the reaction conditions. Starting from As4S4 or As4S3 and 1b insertion of a Cp(x)Co(CO) fragment into one of the As-As bonds of the cages was achieved in low yields leading to Cp(x)Co(CO)As4S4 2b and Cp(x)Co(CO)As4S3 8, respectively. Structures were studied by means of IR and H-1-NMR spectroscopy and X-ray diffraction analyses. Cp(2)(#)(CO)As2S2 3 may be supposed to be the key intermediate in the whole reaction sequence: On heating solutions of 3 complexes 4-6 of higher nuclearity and different connectivity within the inorganic ligand were formed.
