Abstract
Reaction of [Mo{η5-C5(CH3)5}(Br)(CH3)(NO)]2 (I) with air in sunlight gives a mixture of two oxo complexes: [Mo{C5(CH3)5}(Br)(O)2] (III) and [Mo{η5-C5(CH3)5}(O)2](μ-O))) (IV). The X-ray structure of IV shows a space group P21/a, with a 17.660(1), b 9.238(1), c 21.277(1) Å, β 101.79(1)°, and Dcal 1.590 g cm−3 for Z = 6. A final R value of 0.064 (Rw = 0.064), based on 3300 observed reflections was obtained. The dimeric molecule can be regarded as made up of two distorted tetrahedra which share a common oxygen atom. The asymmetric unit in the unit cell contains 1.5 dimeric molecules.
