Synthesis and characterisation of Mn(II), Co(II), Ni(II),Cu(II) and Zn(II) bis- chelates of 8-quinolinyloxyacetic acid and a few mixed ligand complexes of Cu(ll) with 8-quinolinyloxyacetic acid

Abstract

Manganese(II), cobalt(II), nickel(II) and zinc(II) complexes of the type [M(EHQ)₂(H₂O)₂] and Cu(EHQ)₂ with the ligand 8- quinolinyloxyacetic acid(EHQH) have been isolated and characterized on the basis of elemental analyses, spectral, magnetic and thermal data. Copper(Il) mixed ligand complexes of the type [Cu(EHQ)L(H₂O)], where LH = 8-hydroxyquinoline(oxineH) /1-acetyl-2-naphtholoxime (OATNOH) /salicylaldehyde phenylhydrazone (SalphH) have also been characterised similarly.
