The new lamellar phases [Zn(2,2-bpy) 2(H 2O) 2](ZrF 6)·3H 2O (I) and [Ni(2,2-bpy) 3](MoO 2F 4)·5H 2O (II) (bpy = bipyridine), which are built from a chiral cation and respectively an inherently nonpolar and a polar anion, provide two contrasting structures with respect to chirality and polarity in the solid state. Each nonpolar layer of I contains enantiomers of both handednesses; conversely, each layer of II contains only a δ or λ enantiomer and polar anions oriented along the b or -b axes. A comparison with previously reported structures reveals which combinations and interactions between chiral and polar basic building units can preserve elements of polarity and chirality in the solid state.
