Two (1,3.4)-oxadiazole ligands have been prepared. In one case the oxadiazo
le ring is flanked by two o-aniline groups, and in the other case it is an
extension of the first where the amines are condensed with 2-picolyl groups
. A monometallic copper(II) complex of the former has been prepared, and it
s crystal structure was determined. A number of bimetallic copper(II), coba
lt(II), and nickel(II) complexes of the di-deprotonated latter ligand were
prepared and isolated. The crystal structure of the cobalt(II) complex bear
ing two acetate bridges is reported. The work demonstrates that the seldom-
employed oxadiazole ring can be used effectively for generating bimetallic
complexes.
