Three routes to the synthesis of the cobalt(I) thiocarbonylBPh4 (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 + cations of the two molecules exhibit trigonal bipyramidal geometry around the cobalt atoms with the Co-CS fragments in alinear arrangement.

Reaction of (np3)CoH (1) [np3 = tris[2-(diphenylphosphino)ethyl]amine] with CS2, SCNPh, or OCNPh affords (np3)Co(η2-CS2) (2), (np3)Co(η2-SCNPh) (6), and (np3)Co(η2-OCNPh) (8), respectively. In the presence of NaBPh4 1 reacts with CS2 or SCNPh to give [(np3)Co(CS)]BPh4 (3) and [(np3)Co(CNPh)]BPh4 (7), respectively, and with OCNPh or COS to give [(np3)Co(CO)]BPh4 (4). Methylation of 2 by MeSO3F, followed by NaBPh4 addition, leads to [Ph2PCH2CH2N(CH2CH 2PPh2)2Co(CS2Me)]BPh4 (5) through intramolecular attack by a phosphorus atom of np3 on a formed in situ η2-dithiomethyl ester group. On reaction of 5 with NaBH4 the P-CS2Me and C-SMe bonds are cleaved and the thiocarbonyl complex 3 is formed.
