A new macrocyclic ligand 1-[5-(1-{2-[1-(5-acetyl-2,4-dihydroxy-phenyl)-ethylideneamino]-phenylimino) -ethyl)-2,4 dihydroxy-phenyl]-ethanone was prepared by condensation of ethanolic solutions of 4,6- diacetyl resorcinol ando-phenylenediamine. The ligand was characterized by1H- &13C- NMR, IR, Mass spectral data and analytical data. Metal complexes with this new macrocyclic ligand have been prepared with VO(IV), Mn(II), Fe(II), Co(II), Ni(II), Cd(II) and Cu(II). The metal chelates were

The ligand and the complexes were screened for anti fungal activity against Aspergillus terreus. The order of inhibition has been found to be Cu(II) >Cd(II) >Co (II)>VO (IV)>Fe (II)>Ni (II)>Mn (II)>Ligand.
