Abstract
A 2D lamellar supermolecular complex [Cu(C6H4NO2)2 · H2O] was synthesized and characterized by elementary analysis, infrared spectrum, ultraviolet spectrum, thermogravimetry analysis and crystal X-ray diffraction analysis. The complex belongs to the orthorhombic system, Pbca space group, with a = 1.2797(8), b = 1.2944(8), c = 1.4962(9) nm, Z = 8, V = 2.478(3) nm3, D c = 1.746 g cm−3, μ = 1.784 mm−1, F(000) = 1320, R 1 = 0.0267, wR 2 = 0.0762, GOOF = 1.015, which consists of a Cu(II) ion, two 2-Picolinic acid and a coordinated water molecule. The 5-coordinated geometry of the Cu cation is a distorted tetragonal-pyramidal configuration. The 1D chain structure is formed through hydrogen bonds O(w)-H…O between single cells, and the 2D lamellar supermolecular system is formed through the non-classical hydrogen bonds C-H…O between various chains. The complex displays a distinct absorption band (λmax = 648 nm) in aqueous solution. The electrochemical behavior shows a quasi-reversible course. (CCDC: 750880)
