Mo(NAr)(OSiPh3)2(C8H14) shows a weak absorption at ∼477 nm for what we propose is a σMoC → dxy transition, which is a shift in λmax of ∼100 nm from where the analogous transition is found in the 8-tungstabicyclo[4.3.0]nonane analogue (∼380 nm). The rate of formation of Mo(NAr)(OSiPh3)2(CHC7H13) from Mo(NAr)(OSiPh3)2(C8H14) is ∼20% of the rate found for the tungsten analogue. A 7-molybdabicyclo[3.3.0]octane complex,
