The new salicylaldimine, as O,N-bidentate ligand (HL), containing amino acide ester and its Ru(II) complex [Ru(bpy)(2)(HL)]Cl-2 have been prepared. Synthesized compounds have been structurally characterized by IR, H-1 NMR, LC-MS, fluorescence spectroscopy, elemental and thermal (TGA-DSC) analyses. The metal to the ligand ratio of the Ru(II) complex was found to be 1:1. Antifungal activities of the ligand and complex have been investigated. The Ru(II) complex have strong antifungal activity than the ligand against Aspergillus niger.
