摘要：

Crystals of triethylamine-(tricobalt enneacarbonyl carbon)oxyborane, Co3(CO)10BH2N(C2H5)3, have been prepared by the reaction of triethylamine-borane with dicobalt octacarbonyl in benzene. The molecular and crystal structures of this compound have been determined from three-dimensional X-ray counter data. Crystals of the dark red, air-stable compound are monoclinic with cell dimensions of a — 11.75 ± 0.01 Å, b = 11.29 ± 0.01 Å, c = 8.81 ± 0.01 Å, and β = 93.31 ± 0.05°. The space group is P21/m with two formula species per cell imposing Cs point symmetry on the individual molecules. The structure has been refined by least squares to a conventional R of 0.087. The basic structural feature consists of a triangular cluster of cobalt atoms each coordinated to three carbonyl groups and an apical triply bridging CO group with a C-O bond distance of 1.28 Å. The infrared and mass spectral data are given for this material, and the structure is compared with the related Co3(CO)9CCH3 and Co3(CO)9S molecular complexes. © 1968, American Chemical Society.
