Enantioselective Self‐Assembly of Bimetallic [MnII(Δ)‐CrIII(C2O4)3]−and [MnII(Λ)‐CrIII(C2O4)3]−Layered Anionic Networks Templated by the Optically Active (Rp)‐ and (Sp)‐[1‐CH2N(n‐C3H7)3‐2‐CH3C5H3FeC5H5]+Ions

The ferrocenic ammonium (Rp)‐ and (Sp)‐[1‐CH2NR3‐‐2‐CH3C5H3FeC5H5] iodide salts with R=CH3, C2H5, n‐C3H7, n‐C4H9, were synthesized starting from the (Rp)‐ and (Sp)‐[1‐CH2N(CH3)2‐2‐CH3C5H3FeC5H5] amines obtained in their optically active forms through asymmetric cyclopalladation of [C5H5FeC5H4CH2N(CH3)2]. 1H NMR studies of these planar chiral 1,2‐disubstituted ferrocenic ammonium iodide salts in the presence of the (Δ)‐(tris(tetrachlorobenzenediolato)phosphate(V) anion), [(Δ)‐Trisphat] support the formation of specific diastereomeric ion pairs. Such intermolecular interactions can be related to the self‐assembly of the two‐dimensional optically active compounds {[(Sp)‐1‐CH2N(n‐C3H7)3‐2‐CH3C5H3FeC5H5][Mn (Δ)‐Cr(C2O4)3]} and {[(Rp)‐1‐CH2N(n‐C3H7)3‐2‐CH3C5H3FeC5H5][Mn (Λ)‐Cr(C2O4)3]} starting from the resolved (Rp)‐ and (Sp)‐[1‐CH2N(n‐C3H7)3‐2‐CH3C5H3FeC5H5]+ion associated to the racemic anionic building block rac‐[Cr(C2O4)3]3−and Mn2+. Both enantiomeric forms of the networks behave as ferromagnets with a Curie temperature of 5.7 K.
