Synthesis and Reactions of bis(arylimino)isoindoline Complexes of Dimolybdenum
Inorganica Chimica Acta
Several dimolybdenum complexes have been synthesized which contain the planar tridentate ligand bis(arylimino)isoindoline, BAII. The BAII derivatives which have been successfully coordinated to the dimolybdenum unit include those in which the aryl group is pyridine, 4-methylpyridine, and 4-ethylpyridine. It was found that only one BAII ligand would attach to the dimolybdenum unit and that complexes with the formula Mo2(OAc)3(BAII) resulted. These complexes have one molybdenum coordinated to the BAII and one monodentate acetate while the other molybdenum is coordinated to two bidentate acetates. This structural assignment is supported by NMR, infrared and electronic absorption data. This is the first dimolybdenum complex which contains non-bridging acetates as well as being the first dimolybdenum complex with a planar tridentate ligand. Reaction of the complexes with excess acetic acid regenerates molybdenum acetate thus showing that the quadruple bond is intact in the BAII complexes.
