Abstract

A novel dipodal Pseudoceratidine analogue MPPy [N1,N3-bis(3-(((E)-(1H-pyrrol-2- yl)methylene)amino)propyl)malonamide] has been synthesized. Different spectroscopic techniques such as 1H NMR, 13C NMR and IR spectroscopy were used to characterize the ligand. Coordination behavior of the ligand with Zn (II) was studied potentiometrically and spectrophotometrically in highly aqueous medium at room temperature. A high binding constant (logβ= 31.68) shows an effective encapsulation of Zn (II) by ligand MPPy in 1:1 stoichiometry. Computational studies of the ligand as well as its complex with Zincwas done using semi-empirical method. PM6 parameter was used for structure optimization of the ligand.
