Crystal structures of ( <i>S</i> )-(−)-1-(4-chlorophenyl)- <i>N</i> -[(pyridin-2-yl)methylidene]ethan-1-amine and its <i>cis</i> -dichlorido{( <i>S</i> )-(−)-1-(4-chlorophenyl)- <i>N</i> -[(pyridin-2-yl)methylidene]ethan-1-amine}palladium(II) complex
One of the title compounds, the chiral Schiff base (<i>S</i>)-(-)-1-(4-chloro-phen-yl)-<i>N</i>-[(pyridin-2-yl)methyl-idene]ethan-1-amine (C<sub>14</sub>H<sub>13</sub>ClN<sub>2</sub>) crystallizes in the monoclinic Sohncke space group <i>P</i>2<sub>1</sub> with one mol-ecule in the asymmetric unit. The ligand is obtained by condensation of (<i>S</i>)-(-)-1-(4-chloro-phen-yl)ethan-1-amine with 2-pyridine-carboxaldehyde. Its palladium(II) chloride complex, <i>cis</i>-di-chlorido-{(<i>S</i>)-(-)-1-(4-chloro-phen-yl)-<i>N</i>-[(pyridin-2-yl)methyl-idene]ethan-1-amine-κ<sup>2</sup> <i>N</i>,<i>N</i>'}palladium(II), [PdCl<sub>2</sub>(C<sub>14</sub>H<sub>13</sub>ClN<sub>2</sub>)], crystallizes in the ortho-rhom-bic Sohncke space group <i>P</i>2<sub>1</sub>2<sub>1</sub>2<sub>1</sub>, with one mol-ecule in the asymmetric unit. The central Pd<sup>II</sup> atom adopts a slightly distorted square-planar coordination environment, defined by two nitro-gen donors (pyridyl-N and imine-N) and two chlorido ligands in a <i>cis</i> arrangement.
