A variety of α-dicarbonylbis(aroylhydrazone) H2L (1) ligands were synthesized and used to synthesize complexes formulated as NiL-nH2O, Zn2L2 · nH2O, CuL, CoL · nH2O and Na[CoL(NO2)2], where L refers to the dinegative anion of α-dicarbonylbis(aroylhydrazone) ligand. These complexes were investigated by elemental analyses, IR and UV-vis spectra and, for zinc(II), Na[CoL(NO2)2] and the anhydrous NiL complexes, 1H NMR spectra were measured in order to elucidate their structures. Other octahedral complexes such as Ni(H2L)2(OAc)2 and Co(HL)3 · nH2O were isolated and characterized. Different modes of coordination were assigned to the ligand 1 and its anions in the isolated complexes; dinegative tetradentate, mononegative bidentate and neutral bidentate.
