Synthesis and Properties of Coordination Compounds of Co(II) and Ni(II) with Some Hydrazone Derivatives
نویسندگان
چکیده
Reaction of some aroylhydrazones with Co(II) and Ni(II) salts were investigated and the corresponding complexes were isolated. Magnetic and spectral data showed that in the case of metal chloride and nitrate octahedral complexes were formed, with Iigands coordinated as neutral molecules. In the case of Ni(II) acetate square planar complexes and with Co(lI) acetate paramagnetic complexes were obtained, all of them with deprotonated Iigands.
