Dioxidomolybdenum(VI) complex featuring a 2,4-di­fluoro-substituted amine bis­(phenolate) ligand

ABSTRACT: An updated structure is reported for a bis­(oxo) MoVI complex that is modeled after the molybdenum cofactor. An analysis of lengths and angles suggests that this dataset offers a more accurate depiction of bonding for the MoVI=O moiety. Synthetic complexes containing a cis-[MoO2]2+ core are well-established models for the molybdenum co-factor (Moco). Here we report the crystal structure of such a model complex bearing a tetra­dentate amine bis­(phenolate) ligand with fluorine substituents on the phenolate rings, namely, [2,2′-({[2-(di­methyl­amino)­eth­yl]aza­nedi­yl}bis­(methyl­ene))bis­(4,6-di­fluoro­phenolato)]dioxidomolybden­um(VI)), [Mo(C18H18F4N2O2)O2]. Distortion from idealized octa­hedral symmetry about the Mo center is evident in the large O=Mo=O angle [108.54 (4)°] and the small
