Allyl complexes of molybdenum with Schiff base ligands. The crystal structures of [MoCl(CO) 2{N(C 6H 4-2-OMe)C(Me)C 5H 4N}(η 3-C 3H 5)] and [MoCl(CO) 2{N(Me)C(Ph)C 5H 4N}(η 3-C 3H 5)] are described

Abstract

Treatment of the molybdenum tetracarbonyl complexes of [Mo(CO) 4L 2] (L 2=pyridyl amine Schiff base ligands) with allyl chloride in refluxing THF afforded η 3-allyl complexes [MoCl(CO) 2L 2(η 3-allyl)] ( 1– 9). These complexes have been characterised by various techniques including 1H-NMR, IR and FABMS spectroscopies and the single crystal X-ray structure determinations of the complexes [MoCl(CO) 2{N(C 6H 4-2-OMe)C(Me)C 5H 4N}(η 3-C 3H 5)] ( 3) and [MoCl(CO) 2{N(Me)C(Ph)C 5H 4N}(η 3-C 3H 5)] ( 4).
