title: A chiral luminescent coordination polymer featuring a unique 4-connected self-catenated topology built from helical motifs.
abstract: The luminescent chiral coordination polymer {[Cd(pht)(dpa)(H(2)O)] x 4 H(2)O}(n) (pht = phthalate; dpa = 4,4'-dipyridylamine) possesses an unprecedented 4-connected uninodal self-catenated three-dimensional 7(4)8(2) network topology, constructed from the interlocking of [Cd(dpa)](n) double helices with [Cd(pht)](n) single helices.
