Synthesis of V-shaped Schiff base ligand of type (N1E,N2E)-N1,N2-bis(pyridin-2-yl-methylene)-ethane-1,2-diamine, DFT/XRD/HAS analysis

Abstract

A new functionalized V-shaped Schiff base (N¹E,N²E)-N¹,N²-bis(pyridin-2-ylmethylene)ethane-1,2-diamine ligand was synthesized in good yield via condensation of picolinaldehyde with ethane-1,2-diamine in ethanol solution under open reflux condition. The prepared N4-SB was characterized by XRD single crystal then computed via Hirshfeld surface analysis (HSA). Moreover, the two-dimensional fingerprint (2D-FP) and structural DFT optimization processes were also performed. The DFT structural parameters like bonds and angles lengths were matching with their XRD experimental relatives.
