Supramolecular assembly of two two-folded helical structures based on 2-substituted 8-hydroxyquinoline complexes

摘要: Abstract Based on two 2-substituted 8-hydroxyquinoline ligands containing NO2 and Cl, complexes [Co(L2)2(pyridine)2] (1) [Cu(L3)2] (2) were synthesized characterized with single-crystal X-ray diffractions, powder diffractions (PXRD), thermal analyses (TGA) elemental (EA). In the solid state, supramolecular structures of 1 2 feature different two-folded helical chains, which constructed by non-covalent interactions, such as π⋯π stacking, C H⋯π, H⋯O, Cl⋯π Cl⋯Cl interactions. The present research holds great promise in development novel functional structure, may contribute to understanding organized systems biology.
