Reduction of the cobalt(II) complexes BPh4 with sodium amalgam gives tetrametallic complexes of formula .The structure of 2(μ-Hg2)>*thf was determined from three-dimensional X-ray data collected by the counter method.The crystals are triclinic, space group P1, with a = 25.691(9), b = 13.387(5), c = 13.471(4) Angstroem, α = 119.56(8), β = 97.51(8), γ = 87.25(7) deg, and Z = 2.Full-matrix least-squares refinement converged at the conventional R factor of 0.067 for 2 687 observed reflections.The structure consists of dimeric units of 2) where the Hg2(2+) ion linearly bridges two Co(dppea) fragments.The dppea derivative reacts with carbon monoxide or carbon dioxide, at room temperature and atmospheric pressure, with formation of the carbonyl complex BPh4.

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.
