Reactions of ketones with molybdenum nitrosyl complexes: X-ray crystal structures of [{Mo{HB(3,5-Me2C3HN2)3}(NO)I}2O], a complex having a bent Mo–O–Mo bond, and of a bicyclic salt, [C6H3Me5N2(OH)][I1/2(I3)1/2]

Abstract

Reaction of [Mo{HB(3,5-Me₂C₃HN₂)₃}(NO)I₂] WITH refluxing acetone or diacetone alcohol led to C–C bond cleavage and formation, in low yield, of [{Mo {HB-(3,5-Me₂C₃HN₂)₃}(NO)I}₂(µ–O)] and the bicyclic cation [C₆H₃Me₅N₂(OH)]⁺(isolated as the I^– or mixed I^–/I^–₃ salt); the structures of the last two were determined crystallographically, the µ-oxo species having a slightly bent Mo–O–Mo bond.
