  OCBBCO:  A Neutral Molecule with Some Boron−Boron Triple Bond Character

  摘要：

  Molecules that contain boron-boron multiple bonds are extremely rare due to the electron-deficient nature of boron. Here we report experimental and theoretical evidence of a neutral OCBBCO molecule with some boron-boron triple bond character. The molecule was produced and unambiguously characterized by matrix isolation infrared spectroscopy. Quantum chemical calculations indicate that the molecule has a linear singlet ground state with a very short boron-boron bond length.

  Infrared spectra were obtained for Ar/CO samples codeposited with laser ablated boron atoms on a 12 +/- 1 K salt window. BCO was identified as the primary reaction product, based on isotopic substitution at all atomic positions and ab initio structure and frequency calculations. The dicarbonyl, B(CO)2, and the linear dimer, (BCO)2, were also identified from the infrared spectra. A higher cluster species containing bridging carbonyls appeared on annealing and was stable until the matrix sublimed away.
