A coordination compound of (-)-ephedrine and palladium(II)

The reaction of (-)-ephedrine with PdCl2 in the presence of NaPF6 leads to chloro[(1R,2S)-2-methylamino-1-phenylpropan-1-ol-N][(1R,2S)-2-methylamino-1-phenylpropan-1-olato-N,O]palladium(II), [PdCl(C10H14NO)(C10H15NO)]. The crystal structure determination shows two (-)-ephedrine [(1R, 2S)-2-methylamino-1-phenylpropan-1-ol] ligands, one as a chelating moiety and the other as a monodentate ligand in which only the N atom is coordinated to the Pd-II atom. An extensive hydrogen-bond network ensures the three-dimensional cohesion of the atomic arrangement.
