Synthesis, characterization and crystal structure determination of a new Zn(II) Schiff base complex derived from condensation of a new asymmetrical tripodal amine, 3-((4-aminobutyl)(pyridin-2-ylmethyl)amino)propan-1-ol and 2-hydroxy-3-methoxybenzaldehyde

Abstract

A new tripodal amine, 3-((4-aminobutyl)(pyridin-2-ylmethyl)amino)propan-1-ol (HL) has been prepared. This has been used to synthesize a new Schiff base complex by template condensation with 2-hydroxy-3-methoxybenzaldehyde in the presence of Zn(II) metal ion in methanol. The complex has been characterized using spectroscopic methods and the crystal structure of [ZnL]BF4, L:3-((4-aminobutyl)(pyridin-2-ylmethyl)amino)propan-1-ol was confirmed by single crystal X-ray diffraction studies. Single crystal X-ray structure analysis showed that in the mononuclear Zn(II) complex, [ZnL]BF4 the Zn(II) ion is in a distorted square pyramidal environment.
