The behavior of some transition metal cations [Cr (III), Fe (III), Fe (II), Co (II), Ni (II) and Cu (II)] were investigated in ammonium alum-urea ionic liquid. The study was followed by UV-Visible electronic spectroscopy to establish their coordination geometry in the liquid and estimate the ionic species attached to the transition metal cations. The reactivity of the metal cations were found to vary from one to another. Chromium (III) cation was found, (as expected) to be in octahedral geometry with ionic liquid species and was inert toward the addition of ligands.
