ABSTRACT:

Several new metal complexes of Fe(III), Ni(II), Zn(II), Ru(III) and Pd(II) with hydrazones derived from (3,4-dihydro-3-oxo-2H-1,4-benzoxazin-2-yl)acetic acid hydrazide and benzaldehyde, salicylaldehyde and furfuraldehyde and reported. The ligands co-ordinate with the metal ions in neutral, bidentate / mononegative, tridentate manner. The Fe(III), Ni(II) and Ru(III) complexes are found to be octahedral, Pd(II) complexes square planar and the Zn(II) complexes tetrahedral.
