Synthesis, crystal structure, Hirshfeld surface analysis and magnetic studies of bis[1,3-dicyclohexyl-2-ethyl isouronium]tetrachlorocobaltate(II)

Abstract

In this research work, a new inorganic-organic hybrid material bis[1,3-dicyclohexyl-2-ethyl isouronium]tetrachlorocobaltate(II), (C15H29N2O)2CoCl4 has been successfully synthesized and good quality crystals have been grown by slow evaporation solution technique. The structure was determined by single crystal X-ray diffraction at room temperature. This compound crystallizes in the triclinic crystal system with space group Pī. The atomic arrangement of the title compound can be described as an alternation of organic and inorganic layers along the a−axis, which are interconnected via N–H⋯Cl hydrogen bonds. The thermal stability of the grown crystal was evaluated using thermo-gravimetric and differential scanning calorimetric analyses (TG/DSC). The Hirshfeld surface analysis was conducted to investigate intermolecular interactions and associated 2D fingerprint plots, revealing the relative contribution of these interactions in the crystal structure quantitatively. The magnetic susceptibility measurements in the temperature range 2–300 K shows that the complex displays a weak antiferromagnetic exchange interaction at low temperature.
