Synthesis, Crystal Structure, Spectroscopic Properties, and Interaction with Ct-DNA of Zn(II)‎ with 2-Aminoethanethiol Hydrochloride Ligand

Abstract EN

The zinc(II) complex (C2H6NS)2Zn·ZnCl2 was synthesized with 2-aminoethanethiol hydrochloride and zinc sulfate heptahydrate as the raw materials in aqueous solution.

The composition and structure of the complex were characterized by elemental analysis, infrared spectra, single crystal X-ray diffraction, and thermogravimetry.

The crystal structure of the zinc(II) complex belongs to monoclinic system, space group P 21/n, with cell parameters of a = 0.84294(4), b = 0.83920(4), c = 1.65787(8) nm, Z=2, and D = 2.041 g/cm3.

In this paper, the interaction of complex with Ct-DNA was investigated by UV-visible and viscosimetric techniques.

Upon addition of the complex, important changes were observed in the characteristic UV-Vis bands (hyperchromism) of calf thymus DNA and some changes in specific viscosity.

The experimental results showed that the complex is bound to DNA intercalative (intercalation binding).
