A Chiral Luminescent Coordination Polymer Featuring a Unique 4-Connected Self-Catenated Topology Built from Helical Motifs

The luminescent chiral coordination polymer {[Cd(pht)(dpa)(H2O)]·4H2O}n (pht = phthalate; dpa = 4,4′-dipyridylamine) possesses an unprecedented 4-connected uninodal self-catenated three-dimensional 7482 network topology, constructed from the interlocking of [Cd(dpa)]n double helices with [Cd(pht)]n single helices.
