文摘

The combination of transition metal ions with mixed ligands resulted in the formation of three new coordination polymers, {[Co(C₄H₄O₅)(bpe)(H₂O)₂] · (0.5bpe)(H₂O)}_n (1), {[Cu(C₄H₄O₆)(bipy)] · 5H₂O}_n (2) and {[Cu(C₄H₄O₅)(bpa)] · 2.5H₂O}_n (3) (, , bpe = 1,2-bis(4-pyridyl)ethene, bipy = 2,2′-bipyridine, bpa = 1,2-bis(4-pyridyl)ethane), which were prepared under solvothermal conditions and characterized by single-crystal X-ray diffraction. 1 and 2 feature 1D chain structures. Interestingly, each pair of chains recognizes each other through aromatic π–π stacking interactions, generating a zipper-like double-stranded chain in 2. Compound 3 shows 2D 6³ topology framework with a rectangle-like grid.
