A Dioxomolybdenum(VI) Complex with a New Enantiomerically Pure Tetrahydrosalen Ligand

The enantiomerically pure tetradentate ligand H₂L {2,2'-[trans-(R,R)-1,2- cyclohexanediylbis(N-methylaminomethyl)]diphenol}, forms a neutral dioxomolybdenum(VI) complex, which was isolated as {2,2'-[trans-(R,R)-1,2- cyclohexanediylbis(N-methylaminomethyl)]diphenolato-O,N,N',O'}dioxomolybdenum(VI) trichloromethane solvate, [MoO₂(C₂₂H₂₈N₂O₂)].CHCl₃, and characterized by a single-crystal X-ray analysis. The coordination geometry around the metal is distorted octahedral. The two oxo O atoms are cis and the two phenolate O atoms are in (distorted) trans positions. The two N atoms are located approximately trans to the oxo O atoms and the Mo-N bonds are remarkably long.
