Abstract
Pyridoxine (pyH) complexes of zinc(II) and ruthenium(III) have been synthesized and characterized by spectral data including UV-visible, infrared spectroscopy and mass spectrometry. The pyH/py− ligand is coordinated to zinc and ruthenium through N atom of the pyridine ring and O atom of 5′-CH2OH group. The structures have been proposed for the two non-ionic complexes. The Zn(II) complex is found to be diamagnetic whereas the Ru(III) complex is paramagnetic. The antioxidant activity evaluation of pyH, Zn-pyH and Ru-py complexes has been evaluated.
