Enantioselective self-assembly of bimetallic [M-II (Delta)-Cr-III(C2O4)(3)](-) and [Mn-II (Lambda)-Cr-III(C2O4)(3)](-) layered anionic networks tempalted by the optically active (Rp)- and (Sp)-[1-CH2N(n-C3H7)(3)-2-CH3-C5H3Fe-C5H5](+) ions

摘要

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-C5H3FeC5H5] amines obtained in their optically active forms through asymmetric cyclopalladation of [C5H5FeC5H4CH2N(CH3)(2)]. H-1 NMR studies of these planar chiral 1,2-disubstituted ferrocenic ammonium iodide salts in the presence of the (Delta)-(tris(tetrachloro-benzenediolato)phosphate(nu) anion), [(Delta)-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 (Delta)-Cr(C2O4)(3)]} and {[(Rp)-1-CH2N(n-C3H7)(3)-2-CH3-C5H3Fe-C5H5][Mn (Lambda)-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.
