Zinc(II) mediated cyclization product, 3-(1-oxo-1,3-dihydro-isoindol-2-yl)-propionic acid (Hpda) and complexation of the unsymmetrical amino dicarboxylic ligand, N-(2-carboxybenzomethyl)-β-alanine (H2cbal), have been isolated and their crystal structures determined.
Zinc(II) mediated cyclization and complexation of an unsymmetrical dicarboxyamine ligand, N-(2-carboxybenzomethyl)-β-alanine (H2cbal) have been studied in the solid state as well as in solution. The structural analyses reveal that while the cyclized ligand Hpda consists of an 1-oxo-1,3-dihydro-isoindol ring and is not coordinated to any zinc ion, the zinc complex 1 exhibits a three-dimensional coordination polymer constructed from mononuclear building unit, [NaZn(Hcbal)2(ClO4)] · H2O · CH3OH with the zinc center tetracoordinated in a distorted tetrahedral geometry. So, we have been able to isolate and characterise a new cyclized ligand and a new zinc coordination polymer using the reactions of same starting materials, the ligand H2cbal and Zn(ClO4)2 · 6 H2O, under two different reaction conditions.Figure optionsDownload as PowerPoint slide
