Molecular docking with SARS-CoV-2 and potential drug property of a bioactive novel Zn(II) polymer: A combined experimental and theoretical study.

A new Zn(II) coordination polymer based on -phthalato (Phth) and 2-aminopyridine (2-Ampy) viz. {[Zn(2Ampy)(Phth)]∙(HO)]} () has been synthesized at room temperature and characterized by elemental analyses, electronic spectroscopy, FTIR spectroscopy, thermal analysis (TGA/DSC), powder Xray diffraction (PXRD) and single crystal Xray diffraction. The basic trimeric units of form a polymeric chain by N-H⋯O and π⋯π interactions.
