  Photolysis of the Group 6 metal hexacarbonyls in hydrocarbon glasses at 80 K gives rise to species M(CO)n(n= 3–5), presumably weakly solvated, by successive CO loss. Primary and subsequent processes both show photo-reversal. Slow warming leads to recombination, hexacarbonyl precipitation, poorly defined, possibly polymeric species, and formation of species [M(CO)5(OH2)]. Visible-u.v. and i.r. spectra

  the resulting subcarbonyl species adsorbed on NaY and NaX zeolites have been investigated utilizing i.r., temperature-programmed decomposition and X.p.s. techniques. It was found that Mo(CO)6 encapsulated in the NaX zeolite was considerably less stable than that contained in the NaY zeolite, while intermediate subcarbonyl species, Mo(CO)3ads, showed a completely reversed thermal stability. The drastic

  利用红外，程序升温分解和Xps技术研究了Mo（CO）6的分解以及吸附在NaY和NaX沸石上的亚羰基物质。发现包封在NaX沸石中的Mo（CO）6的稳定性远低于NaY沸石中包含的Mo（CO）6，而中间的亚羰基物质Mo（CO）3ads显示出完全相反的热稳定性。X和Y沸石之间的稳定性能的巨大差异被认为是由沸石骨架氧的基本强度的差异引起的。基于红外光谱，提出了Mo（CO）3ads的结构。Xps结果表明吸附的Mo（CO）3 该物种在473 K下分解为Mo-金属聚集体。

• Branching ratios and bond dissociation energies from the excimer laser photolysis of group 6 metal carbonyls

  Photolysis of the group 6 (Cr, Mo, W) metal carbonyls in the gas phase, at excimer laser wavelengths, may lead to more than one primary product. Branching ratios between these products have been measured as a function of photolysis wavelength, buffer gas pressure, and temperature using time-resolved infrared spectroscopy. The results are modeled using a sequential dissociation mechanism in which branching ratios are determined by competition between unimolecular dissociation and collisional relaxation. The sensitivity of the results to thermochemical input parameters and assumptions concerning energy disposal mechanisms is discussed. Under qualified assumptions the branching ratio measurements provide estimates for CO bond dissociation energies for coordinatively unsaturated metal carbonyls. For Mo and W the individual bond dissociation energies are close to the average values but for Cr the first three ligands coordinated are significantly less strongly bound than the last three. This finding is discussed in terms of recent ab initio calculations on bonding in metal carbonyls.
