Four previously reported quadridentate ligands were synthesized, and the attempts made to synthesize the corresponding bis(quadridentate)niobium( IV) complexes are documented. Attempts made to synthesize the previously reported tetrakis(bidentate) niobium ( IV) complexes of benzoyltrifluoroacetylacetone (Nb(BTA)O1 and of 8- hydroxyquinoline (Nb(8-Q)4)t are also discussed. Though neither of the desired complexes was synthesized, the resulting complexes from the attempted synthesis of the Nb(8-Q)4 complex, and their subsequent analyses, are examined in detail. Along with the ligand syntheses and the attempted coraplexations , modifications in the experimental techniques and the apparatus are also discussed .
