Abstract
AbstractA 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 P1¯ 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.

Research interest in coordination polymers has increased recently as a result of their fascinating topologies and intriguing frameworks and due to their potential applications in gas storage, separation, biosensing, luminescence, magnetism, conductivity, nanoparticles, antimicrobialMoise Ondoh Agwara ABOUT THE AUTHORMoise Ondoh Agwara is Associate Professor of Chemistry at the Department of Inorganic Chemistry, University of Yaounde I in Cameroon
The results of the preliminary antimicrobial screening against four pathogenic bacteria and four fungi species indicate that the complex is most active against Salmonella typhi
Taking advantage of the coordination ability and properties of copper, pyridine and SCN, we report the synthesis, crystal structure and the luminescent properties of a thiocyanate-bridged copper(II) coordination polymer with pyridine
Summary
Such interest derives from the fascinating structural chemistry of the complexes obtained, their interesting physico-chemical properties and their diverse applications such as antimicrobials, in photoluminescence and as precursors for the development of nanostructured functional materials. The focus of this paper is the synthesis and determination of the structure and properties (thermal and photoluminescent) of a Cu(II)-pyridine thiocyanate coordination polymer. The results of the preliminary antimicrobial screening against four pathogenic bacteria and four fungi species indicate that the complex is most active against Salmonella typhi.
