A homochiral amino acid coordination network [{Ag3Cu3(l-methioninato)6(NO3)3(H2O)3}·7H2O]n, self-assembled from CuII, AgI,
and l-methionine via a distinct soft−hard recognition process, shows
interesting characteristics, in that it is constructed from 1D helical
building blocks and contains homochiral channels in which 1D water
chains are hosted. This result provides an effective and controllable
strategy for the preparation of enantiopure heterometallic supramolecular structures that are relevant to biopolymers.
