Chirality as a Feature of the Crystal Structure of Lanthanide Ion Complexes—Some Simple Examples

Single-crystal X-ray structure determinations are reported for four lanthanide complexes, [Dy(bipy)2Cl2(OH2)2]Cl.H2O (bipy = 2,2?-bipyridine), 1; [La2(phen)2(O2CCH3)4(NO3)2] (phen 1,10-phenanthroline), 2; [Lu(terpy)(O2CCH3)3].NaNO3 (terpy 2,2?;6?,2?-terpyridine) 3; and [Lu(phen)(O2CH)3(OH2)].H2O, 4. Dispersion interactions within the stacked arrays of coordinated aza-aromatic units found in all complexes appear to be a significant structural influence solid state. For complex 1, there additional beyond dispersion, which suggests that it may means whereby ? ? forms contribute overall chiral nature crystal. These weak intermolecular were investigated detail using Hirshfeld surface analysis.
