Synthesis and spectroscopic characterization of ternary copper(<scp>ii</scp>) complexes containing nitrogen and oxygen donors as functional mimics of catechol oxidase and phenoxazinone synthase

Abstract

Two ternary copper(<sc>ii</sc>) complexes<bold>1</bold>[(Cu₂Me₄en)₄(EDTA)] and<bold>2</bold>[(CuMe₄en)₂(MIDA)] containing the mixed ligand system of 1,1′,4,4′-tetramethylethylenediamine (Me₄en) (L) and<italic>N</italic>-methyliminodiacetic (MIDAH₂) (L′) or ethylenediaminetetraacetic acid (EDTAH₄) (L′) were synthesized.
