We have synthesized various kinds of mixed ligand complexes of Ni (II) and Cu (II) which contain N-alkylated ethylenediamine (diam) and β-diketonate (dik) : general formula M (dik) (diam) X, where X is an anion with or without coordination ability. These complexes and [Fe (CN) 2 (phen) 2] synthesized by Schilt show the characteristic solvatochromism in various organic solvents due to the donor and acceptor abilities of solvents.
These complexes are classified into two types as a color indicator of the solvent polarity : (1) donor indicators, [Ni (dik) (diam)] X and [Cu (dik) (diam)] X where X is a no-coordinating anion, (2) acceptor indicators, [Cu (dik) (diam) X] with a coordinating monodentate anion and [Fe (CN) 2 (phen) 2].
