Theoretical Insights into The Spectroscopic Properties of Aluminium(III) Complexes with Acetylferrocene Semicarboxamide

Abstract

Biological important complexes of aluminium (III) derived from biologically active sulfur donor ligand 1-acetylferrocene hydrazinecarboxamide (LH) have been prepared and investigated using a combination of micro analytical analysis, melting point, electronic, IR, ¹H NMR and ¹³C NMR spectral studies,. Aluminium isopropoxide interacts with the ligand in 1:1, 1:2 and 1:3 molar ratios (metal: ligand) resulting in the formation of coloured products. On the basis of conductance and spectral evidences, a penta coordinated structure for aluminium (III) complexes have been assigned. The ligand are coordinated to the aluminium(III) via the azomethine nitrogen atom and the enolic oxygen atom.
