Allyl complexes of molybdenum with Schiff base ligands.: The crystal structures of [MoCl(CO)2{N(C6H4-2-OMe)=C(Me)C5H4N}(η3-C3H5)] and [MoCl(CO)2{N(Me)=C(Ph)C5H4N}(η3-C3H5)] are described

Treatment of the molybdenum tetracarbonyl complexes Of [Mo(CO)(4)L-2] (L-2 = pyridyl amine Schiff base ligands) with allyl chloride in refluxing THF afforded eta(3)-allyl complexes [MoCl(CO)(2)L-2(eta(3)-allyl)] (1-9). These complexes have been characterised by various techniques including H-1-NMR, IR and FABMS spectroscopies and the single crystal X-ray structure determinations of the Complexes [MoCl(CO)(2){N(C6H4-2-OMe)=C(Me)C5H4N}(eta(3)-C3H5)] (3) and [MoCl(CO)(2){N(Me)=C(Ph)C5H4N}(eta(3)-C3H5)] (4).
