Reactivity of acetone oxime towards oxomolybdenum(VI) complexes. Part 2. Syntheses, crystal structures and reactivity of molybdenum nitrosyl complexes

Abstract

The complexes [Mo(NO)(acac)2(Me2CNO)]1(acac = acetylacetonate), [{Mo(NO)(OR)(Me2CNO)2}2](R = Me 2a or Et 2b) and [Mo2(NO)2(OR)2Cl(Me2CNO)3(Me2CNHO)](R = Me 3a or Et 3b) have been obtained by reductive nitrosylation of [MoO2(acac)2], [NBun4]2[Mo6O19] and [NBun4]2[Mo4O12(Me2CNO)2], respectively, by acetone oxime in methanol or ethanol under reflux. Complex 2a reacts with [NBun4]2[Mo2O7] to yield [NBun4]2[Mo4O10(NO)(OMe)(Me2CNO)2]4. This suggests that the reaction of molybdenum(II) nitrosyl complexes with polyoxomolybdates could be a route to a variety of oxonitrosyl species. Crystal structure determinations for 1, 2b, 3b and 4 give further insight into the rich co-ordination chemistry of acetone oxime and reveal an unprecedented µ3N2O co-ordination mode.
