Description |
The complex (eta(4)-C(4)Me(4))Co(CO)(2)I (I) reacted with excess SnCl(2) in boiling THF to give, through replacement of the iodide ligand by the fragment SnCl 3, the mononuclear complex (eta(4)-C(4)Me(4))Co(CO)(2)SnCl(3) (II) containing the Co-Sn bond (2.459(1)angstrom). In a reaction of complex I with phenyltellurenyl halides PhTeI and PhTeBr, an analogous insertion into the cobalt - iodine bond yielded (eta(-)C(4)Me(4))Co(CO)(2)(TeI(2)Ph) (III) and (eta(4)-C(4)Me(4))Co(CO)(2)(TeBrIPh) (IV), respectively. This type of coordination of the aryltellurenyl halide fragment to the transition metal atom was observed for the first time. X-ray diffraction analysis revealed a substantial shortening of the formally single Co-Sn and Co-Te bonds in complexes II - IV compared to the sum of the covalent radii of the corresponding atoms.
