Crystal structure, optical properties, vibrational, thermal and biological study of a new polymeric Cd(II) hybrid material

Abstract This paper describes a new polymeric one-dimensional chlorocadmate(II) compound synthesized with a slow evaporation method. The crystal structure was determined by single-crystal X-ray diffraction. It crystallizes in the Tetragonal system, P 4/n space group, with the following room temperature cell parameters: a = 15.9451(14) A, c = 11.1726(10) A with Z = 2 and V = 2840.6(6) A3. The examination of the structure shows that the anionic part is formed of covalent polymeric chains of (CdCl5)n and isolated CdCl4 tetrahedrons. Hirshfeld surface analysis was used to verify the contributions of the different intermolecular interactions. UV–Vis measurements were employed to figure out the optical behavior of the reported crystal. The vibrational properties were investigated through IR spectroscopy. TG-DSC thermal analysis revealed that the compound remains stable up to  130 °C. For the in vitro antibacterial activity test, results showed that there is no significant difference (p ≥ 0.05) between the inhibition zones caused by the compound and the amine. However, DPPH and ABTS tests showed that the free radical scavenging activity of the tested compound was higher than the amine.
