Synthesis of a novel chiral ruthenium complex and its crystal structure

One novel chiral ruthenium complex was successfully synthesized from the reaction of chiral bidentate nitrogen ligand with RuCl3·3H2O in ethanol under reflux. Its unique crystal structure was unambiguously disclosed by X-ray analysis. The crystal is orthorhombic, space group P212121 (no. 19), with a=13.337(2), b=15.088(2), c=8.878(2) Å, V=1786.4(5) Å3, Z=4, D=1.702 g cm−3. An interesting additional coordination from an oxygen atom of methoxy group to the Ru metal center was found in this novel ruthenium complex.
