The title cocrystal contains two chiral conformational
diastereomers, viz. (1S,2R,RN)- and (1S,2R,SN)-, of [2,4-ditert-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—HO hydrogen bonds, resulting
in one-dimensional molecular chains. Furthermore, the phenyl
rings are involved in weak T-shaped/edge-to-face – interactions
with each other.
