描述了六种新的自组装超分子含砷和锑穴状配体的合成和X射线晶体结构。对先前报道的 As2L3 和 Sb2L3 穴状配体的分析表明，配体几何形状的微小差异导致配合物的螺旋度和组装配合物内金属配位的立体化学存在显着差异。此外，还描述了一种新的合成路线，该路线涉及将反应物暴露于真空以帮助促进自组装。
The syntheses and X-ray crystal structures of six new self-assembled supramolecular As and Sb-containing cryptands are described. Analysis in the context of previously reported As2L3 and Sb2L3 cryptands reveals that small differences in ligand geometries result in significant differences in the helicity of the complexes and the stereochemistry of the metal coordination within the assembled complexes. Additionally, a new synthetic route is described which involves exposure of reactants to vacuum to help facilitate self-assembly.
