Abstract: Novel coordination compounds of Mn(II), Co(II), and Ni(II) with a new 4-(4-chlorocyclohexyl)-2-oxo-6-(thien-2-yl)-1,2-dihydropyridine-3-carbonitrile ligand (L) were synthesized. M.p., elemental anal., spectroscopic techniques (IR, 1H NMR, UV-visible, and mass spectrometry), molar conductivity and thermo gravimetric analyzes were used to characterize the structures having the formulas: [Mn(L)2(H2O)2]SO4 (1), [Co(L)2(H2O)2]Cl2 (2), and [Ni(L)2(H2O)2]SO4·8H2O (3). The (L) reacts by 1 : 2 ratios with metal ions. Using IR spectral data, it was noticed that L ligand coordinates as neutral NO bidentate along with the oxygen of keto-lactam (NH-C:O) and nitrogen of carbonitrile (C≃N) groups. Compounds 1-3 are electrolytic in nature according to the conductivity measurements. Magnetic moment and UV-Visible data depicts the octahedral environment around the studied metal ion. Moreover, Thermal anal. granted a concept around the decaying manner of L and its complexes. It also assessed the quantity of water mols. in the complexe’s inner and outer spheres. For all complexes an octahedral geometry is proposed. TGA data shows the different degradations steps that were used to calculate valuable thermodn. and kinetic descriptors using two comparable methods. Furthermore, theor. studies by DFT demonstrate a high consistent with the exptl. data. Antimicrobial effectiveness of the L and its metal complexes were examined vs. a diversity of pathogenic G(+ve) and G(-ve) bacteria and fungi. The experimental process involved the reaction of 1-Thiophen-2-yl-ethanone(cas: 88-15-3Electric Literature of C6H6OS)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Reflecting their high stabilities, thiophenes arise from many reactions involving sulfur sources and hydrocarbons, especially unsaturated ones. Thiophenes are classically prepared by the reaction of 1,4-diketones, diesters, or dicarboxylates with sulfidizing reagents such as P4S10 such as in the Paal-Knorr thiophene synthesis.
