Enantiospecific inclusion of chiral 1,2-dichloroethane rotamers in the crystal lattice of chiral square-pyramidal Cu(II) complexes with perfectly polar alignment of guest and host molecules

Abstract

The inclusion compounds, [CuL12(H2O)] ·(P)-C2H4Cl2 and [CuL22(H2O)]·(M)-C2H4Cl 2 (HL1 = N-(2-hydroxy-5-nitrobenzyl)-(-R)-α- methylbenzylamine and HL2 = N-(2-hydroxy-5-nitrobenzyl)-(S)-α- methylbenzylamine), crystallise in the non-centrosymmetric space group C2; intermolecular hydrogen bonding leads to a perfectly polar alignment of both host and guest molecules with enantioselectivity. © The Royal Society of Chemistry 2005.
