Absolute helicity induction: chiral information transfer from metal centre to the framework.

Pseudo-achiral metal-centre driven spontaneous resolution occurred simultaneously in the formation of two Δ- and Λ-isomers of [CdBa(OBA)2(DMF)(CH3OH)(H2O)]·H2O (H2OBA = 4,4'-oxybis(benzoic acid)), which illustrated a clear relationship between chirality and helicity: the absolute sense of a double-helix made of achiral components is induced by metal centres in the two enantiomeric forms.
