Abstract: | The structure of the title compound, hexacarbonyl‐1κ3C,2κ3C‐3(η5)‐cyclopentadienyl]bis(μ3‐selenido)diiron(II)cobalt(II),CoFe2(μ3‐Se)2(C5H5)(CO)6], was redetermined at room temperature and the correct C2/c space group was assumed instead of the previously reported P space group Mathur et al. (1995). Organometallics, 14 , 2115–2118]. Analysis of the literature data showed that the previously reported triclinic parameters correspond to a primitive subcell of the actual monoclinic C‐centred cell with cell dimensions close to those found by us. The title compound appeared to be isostructural with the sulfur–selenium analogue. |
