An enantiomeric pair of sodium(I) organic/inorganic frameworks having novel two-dimensional inorganic comb-like separating layers

An enantiomeric pair of sodium(I) directed organic/inorganic frameworks have been obtained via the Schiff base condensation between terephthaldicarboxaldehyde and sodium salts of D- or L-phenylalanine wherein two novel two-dimensional (2D) inorganic sodium(I) separating layers composed of fully fused twelve-membered [Na6(H2O)12] comb-like rings are constituted. To the best of our knowledge, they are the first structural examples of terephthaldicarboxaldehyde-based chiral Schiff base compounds and 2D [Nax(H2O)y]n robust inorganic frameworks.
