Synthesis, crystal structure, photoluminescent and antimicrobial properties of a thiocyanato-bridged copper(II) coordination polymer

Abstract

<p>A Cu(II) 1D polymer with mixed ligands (SCN⁻ and pyridine) has been synthesized and characterized by elemental analyses, IR, UV–visible and TG-DTA analytical techniques. The crystal structure was determined by single-crystal X-ray diffraction analyses. The complex crystallizes in the triclinic crystal system with space group <math><mrow><mi>P</mi><mrow><mn>1</mn></mrow><mrow><mo>¯</mo></mrow></mrow></math> with one formula unit. Each Cu(II) atom is six coordinate with two N atoms of two pyridine molecules, two N atoms and two S-atoms from bridging SCN anions giving a distorted octahedral geometry with a CuS₂N₄ chromophore. The spectroscopic, photoluminescent and the antimicrobial activities of the synthesized complex were investigated.</p
