Four new complexes, [Zn(cca)(phen)]n (1), [Co(cca)0.5(Hcca)(phen)(H2O)] (2), [Cu(cca)(phen)]n · nH2O (3), and [Mn(cca)(phen)(H2O)]n · 0.25nH2O (4) (H2cca = p-carboxycinnamic acid, phen = 1,10-phenanthroline) were synthesized by hydrothermal reactions and characterized by single crystal X-ray diffraction. Complex 1 is of 3D structure constructed by coordination bonds, while complexes 2–4 consist of 3D supramolecular networks, which are assembled by coordination bonds, hydrogen bonds and π–π stacking interactions. In these complexes, p-carboxycinnamate anions (Hcca− and cca2−) adopt tetradentate, bidentate and monodentate modes to coordinate to metal ions, resulting in variety of supramolecular structures.
The structures of four new supramolecular complexes of p-carboxycinnamic acid and d-block metal ions are reported. Their supramolecular networks are constructed by coordination bonds, hydrogen bonds and π–π stacking interactions.Figure optionsDownload as PowerPoint slide
