Abstract:
The dinuclear copper complex receptor (R) was synthesized using the ligands 4-(di-ethyl-amino)-
2-hydroxybenzaldehyde and benzo [d] thiazol-2-amine. The single crystal X-ray analysis of the
homoleptic bis(μ-oxo)dicopper (II) complex indicated that the ligands are coordinated in an anticonfiguration to each other and have adopted a distorted square-pyramidal environment around
the Cu2+ ion. The X-ray solid state structural analysis and DFT reveals no direct Cu…..Cu linkage
within the complex. The anion recognition ability of the R was studied by UV–vis and fluorescence
spectroscopic in acetonitrile. The results indicated that the new complex R displays a sturdy
sympathy and selectivity for hydroxide ion.
