摘要
The synthesis of Co(II), Ni(II) and Cu(II) complexes with some arylidenebenzothiazolyl hydrazides has been described. Characterization of the so obtained complexes was accomplished by elemental analyses, electronic and ir spectroscopy as well as conductivity measurements. It is found that the ortho-hydroxy derivative acts as monobasic bi-or tridentate ligand whereas other derivatives act as neutral bidentate ligands. A pseudo-tetrahedral structure is proposed for all the prepared complexes. The stoichiometry and formation constants of the complexes formed in solution have been also determined.
