ALTERNATIVE ROUTES TO THE SYNTHESIS OF THE COBALT THIOCARBONYL COMPLEX BPh4. INFLUENCE OF THE Co-H DISSOCIATION PATHWAY ON THE REACTION OF THE HYDRIDE (np3)CoH WITH HETEROCUMULENES (np3 = tris(2-diphenylphosphinoethyl)amine)

Three routes to the synthesis of the cobalt(I) thiocarbonyl<(np3)Co(CS)>BPh4 (I) are described, and their mechanisms briefly discussed.The structure of I has been determined from counter diffraction X-ray data.Crystal data are: a 18.749(5), b 34,494(10), c 18.229(4) Angstroem, β 90.73(2) deg, monoclinic space group P2₁/a, Z = 8.The structure has been solved by direct methods and refined to an R of 0.097 using 1914 reflections with I > 3.5?(I).There are two independent molecules of the complex.The <(np3)Co(CS)>⁺ cations of the two molecules exhibit trigonal bipyramidal geometry around the cobalt atoms with the Co-CS fragments in alinear arrangement.
