Co2(μ-CO)2(CO)4(μ-Ph 2P-NH-PPh2-P,P′)· 1/2C6H5CH3 (4·1/2C6H5CH3) reacts with 2-butine-1,4-diol, HOCH2-C≡C-CH2OH (5), to the dark-red tetrahedrane complex Co2(CO)4(μ-η2,η 2-HOCH2-C≡C-CH2OH-C2,C 3)· (μ-Ph2P-NH-PPh2-P,P′)·THF (6·THF). With t-butylphosphaacetylene, tBu-C≡P (7), 4·THF forms Co2(CO)4· (μ-η2,η2-tBu-C≡P)(μ-Ph 2P-NH-PPh2-P,P′) (8), which also belongs to the tetrahydrane type. The compounds were characterized by their mass, IR, 31P{1H} NMR, 13C{1H} NMR, and 1H NMR spectra. Crystals suitable for X-ray structure analyses have been obtained for 8 from dioxane. The dark red blocks crystallize in the monoclinic P21/c space group with the lattice constants a = 1404,1(5), b = 1330,0(7), c = 2578,8(10) pm; β = 90,82(3)°. Johann Ambrosius Barth 1996.
