| Abstract: | Two 2,4-dihydroxybenzaldehydeglycine(H3L) Schiff base complexes: Cu(Py)2(HL)] (1) and Zn(Py)3(HL)]·2Py (2) (Py=pyridine) have been synthesized and structurally characterized. The single crystal X-ray diffraction analysis reveals that the copper center in complex 1 is five-coordinated in a (O, N) fashion of a distorted square pyramidal geometry, while the zinc center in complex 2 possesses a normal octahedral geometry. Importantly, complex 1 exhibit excellent heterogeneous catalytic performance (Conversion: up to 94.8%; Selectivity: up to 98.3%) in the oxidation of aromatic alcohols using hydrogen peroxide as the oxidant.
