Reduction of the cobalt(II) complexes BPh4 with sodium amalgam gives tetrametallic complexes of formula <(CoL)2(μ-Hg2)>.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)<μ-Hg2)> 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.
