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(II) with 8-quinolinyloxyacetic acid

摘要

Manganese(II), cobalt(II), nickel(II) and zinc(II) complexes of the type [M(EHQ)_2(H_2O)_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(II) mixed ligand complexes of the type [Cu(EHQ)L(H_2O)], where LH=8-hydroxyquinoline(oxineH) /1-acetyl-2-naphtholoxime (OATNOH)/salicylaldehyde phenylhydrazone (SalphH) have also been characterised similarly.
