- Abstract
Two two-dimensional supramolecular copper(II) and cobalt(III) complexes, Cu(L1)2 ( 1; HL1 = 2-hydroxy-3-methoxybenzaldehyde oxime) and [Co(L2)2]2⋅2CH3COOCH2CH3 ( 2; HL2 = 1-(2-{[( E)-3-methoxy-2-hydroxybenzylidene]amino}phenyl)ethanone oxime), have been synthesized via complexation of Cu(II) nitrate trihydrate and Co(II) acetate tetrahydrate with HL. A plausible reaction mechanism for the formation of HL1 is proposed. HL was synthesized and characterized using infrared, 1H NMR and 13C NMR spectra, as well as elemental analysis. Complexes 1 and 2 were investigated using single-crystal X-ray diffraction and have a 2:1 ligand-to-metal ratio. Different geometric features of both complexes are observed. In their crystal structures, 1 and 2 form infinite two-dimensional structures and 2 forms a three-dimensional supramolecular framework. Electron paramagnetic resonance spectra of 1 and 2 were also investigated. Moreover, thermal and electrochemical properties and antimicrobial activity of 2 were also studied. In addition, the calculated HOMO and LUMO energies show the character of complex 1.
