摘要

Two three-dimensional frameworks composed of doubly interpenetrating networks of the same topology but different stereoisomeric structures have been constructed from self-assembly of the chiral building block, Δ-or Λ-[Nd(ntb)2]3, with different spacers bipy and bpen (ntb=tris(2-benzimidazolylmethyl)amine, bipy=4,4 -bipyridyl, bpen=trans-1,2-bis(4-pyridyl)ethylene). In the crystal structure of [Nd(ntb)2][ClO4]3 3bipy 2H2O the spacer bipy connects [Nd(ntb)2]3+ cations of the same handedness to generate a chiral network Δ3-Δ... (or Λ3-Λ...){[Nd(ntb)2]3+ 3bipy}∞, which is interpenetrated further by another identical network. The crystal structure of [Nd(ntb)2][ClO4]3+ 3bpen H2O shows a topologically similar but achiral framework in which each spacer bpen connects either cations of the same chirality or a pair of enantiomers, thus generating a three-dimensional racemate Δ2Λ-Λ... (or Λ2Δ-Δ...)- {[Nd(ntb)2]3+ 3bpen}∞. Aggregation of the molecular species is effected by N-H... N hydrogen bonds, and the observed enantioselective self-assembly can be rationalized by π...π interactions between aromatic rings.
