Synthesis, characterization, antibacterial, and antifungal activities of one-dimensional O-H center dot center dot center dot O hydrogen-bonded Cu(II) and Ni(II) complexes
MetadataShow full item record
Two Schiff base complexes, [Cu(HL)(2)], 1 and [Ni(HL)(2)], 2 [H2L = 2-((E)-(2-hydroxyethylimino)methyl)-1-naptaphenol] have been synthesized and characterized by elemental analysis, H-1 NMR, C-13 NMR, IR spectroscopy, and X-ray diffraction. In the crystalline architecture of 1 and 2, intermolecular O-HO hydrogen bonds link the molecules which form one-dimensional polymeric chain structure along the c axis. C-HO and C-H intermolecular interaction also connect the molecules in the structures which form to 3D structures of 1 and 2. The ligand and metal complexes 1 and 2 were screened for antibacterial and antifungal activities.
