A cocrystal of two MoVI complexes bearing different diastereomers of the 2,4-di-tert-butyl-6-{[(1-oxido-1-phenyl­propan-2-yl)(meth­yl)amino]­meth­yl}phenolate ligand derived from (+)-ephedrine

Abstract: The title cocrystal contains two chiral conformational diastereomers, viz. (1S,2R,RN)- and (1S,2R,SN)-, of [2,4-di-tert-butyl-6-{[(1-oxido-1-phenyl­propan-2-yl)(methyl)amino]methyl}phenolato](methanol)-cis-dioxidomolybdenum(VI), [Mo(C25H35NO2)O2(CH3OH)], representing the first example of a structurally characterized molybdenum complex with enanti­omerically pure ephedrine derivative ligands. The MoVI cations exhibit differently distorted octa­hedral coordination environments, with two oxide ligands positioned cis to each other. The remainder of the coordination comprises phenoxide, alkoxide and methanol O atoms, with an amine N atom completing the octa­hedron. The distinct complexes are linked by strong inter­molecular O-H...O hydrogen bonds, resulting in one-dimensional mol­ecular chains. Furthermore, the phenyl rings are involved in weak T-shaped/edge-to-face [pi]-[pi] inter­actions with each other.

Formula: [Mo(C25H35NO2)O2(CH4O)]
