Binuclear copper(II) complexes 1: Synthesis, characterization and evaluation of a new complex in phosphatase-like activity

A new binuclear Cu(II) complex derived from a pamoic type ligand has been synthesized and characterized by X-ray crystallography. This complex was checked as catalysts in the hydrolysis of bis(p-nitrophenyl)phosphate. Its catalytic properties were studied at various pH and compared to the mononuclear Cu(II) complex. At pH 5.38, the binuclear Cu(II) complex exhibited a phosphatase-like activity with 11 TON and 24% conversion and was found to be 41-fold more active than the mononuclear counterpart.

A new binuclear Cu(II) complex derived from a pamoic type ligand has been synthesised, characterised by X-ray crystallography and checked as catalysts in the hydrolysis of bis(p-nitrophenyl)phosphate (BNPP). At pH 5.38, this complex exhibited a remarkable phosphatase-like activity with 11 TON and 24% conversion and was found to be 41-fold more active than its mononuclear counterpart.Figure optionsDownload as PowerPoint slideHighlights
