Biologically important Schiff base ligand 3-phenyl imino 2-indolinone hydrazone (PIIH) have been synthesized by condensation of 3-phenyl imino-2-indolinone with hydrazone hydrate. The metal chelates of PIIH with bivant transition metal ions. Cu(II), Ni(II) and Cu(II) have been synthesized. The structure of Schiff base and their metal chelates have been characterized by elemental analyses, molar mass, IR and electronic spectra, magnetic susceptibility and molar conductivity values. These studies indicate that the compound PIIH acts as neutral bidentate ligand and coordination proposes through indoline N and azomethine N of hydrazone moiety. The rest of coordination position of metal ions are satisfied by neutral ligands such as ammonia, pyridine, a-picoline, b-picoline and g-picoline. The chelates of Co(II), Ni(II) and Cu(II) proposed to be octahedral in geometry.
