Abstract: In this work, we have discussed the chiral transference and recognition effect occurring in several layered aluminophosphates templated by optically pure or racemic mixture of chiral cobalt complexes. These aluminophosphates are Co(tn)(3)-Al3P4O16-2H(2)O (1), d-Co(en)(3)-Al3P4O16-3H(2)O (2), trans-Co(dien)(2)-Al3P4O16-3H(2)O (3) and Co(en)(3)-Al3P4O16-3H(2)O (4). All these layered structures are featured by a series of chiral inorganic structural motifs. It is found that the absolute configuration of the complex template determines that of the inorganic structural motif. A Delta or Delta configuration metal complex can accordingly induce a Delta or Delta configuration inorganic structural motif and a pair of enantiomers of chiral metal complexes can induce a pair of enantiomers of chiral inorganic structural motifs. The chiral recognition effect is studied by molecular mechanical calculation in terms of the host-guest non-bonding interaction.
