Abstract

Photochemically-initiated oxidative fission of the MoMo bond in [C5H5Mo(CO)3]2 by the ferricenium salt [(C5H5)2Fe]BF4 in the presence of four equivalents of L affords a good yield of [C5H5Mo(CO)2L2]BF4 (L = group 15 donor ligands). 95Mo NMR data are reported and discussed together with the NMR and IR data of new complexes. Decomposition of the title cations in polar solvents affords low yields of the corresponding [C5H5MO(CO)3L]BF4 complexes. The X-ray crystal structure of [C5H5Mo (CO)3{P(C6H5)3}]BF4 is reported. The cation has the CpML4 piano-stool geometry.

      The crystal structure of the phenyl derivative showed a pseudo-octahedral geometry at iron and an iron-bismuth bond length of 2.570(1) Å, consistent with a largely σ-bonded system. A similar methodology was employed by Levason, who used the THF adducts of the group 6 metal carbonyls and BiPh3 to prepare [(CO)5MBiPh3] (M = Cr, Mo, W), the coordination of BiPh3 to molybdenum carbonyl compounds had previously been reported by Houk and Dobson and also by Schumann [115–119]. The crystal structures of the Mo and W compounds show an octahedral geometry at the metal centre, with BiPh3 occupying an axial position, which is reflected in an increase of the 1JW–C coupling constant for the trans carbonyl.
