    Synthesis, Characterization and Electrical conductivities of the Complexes of Nickel(II), Copper(II) and Zinc(II) with 2,5-diamino-3,6-dichloro-1,4-benzoquinone
    (World Researchers Associations, 2024) Kushwaha A.; Smriti D.; Prasad R.L.
    Complexes of the type [M(dadb)] (M = Ni(II), Cu(II) and Zn(II)) with ligand 2,5-diamino-3,6-dichloro-1,4-benzoquinone (dadb) have been synthesized and characterized by microanalysis, magnectic susceptibility, electronic, IR, ESR spectroscopy techniques, thermogravimetric analysis (TG), differential thermal analysis (DTA), X-ray powder diffraction (XRD) and solid phase conductivity measurements. The room temperature ESR spectra of Cu(II) complex yield values, characteristics of square planar geometry. The solid state electrical conductivities of the complexes increase as the temperature increases from 311-383 K, with a band gap of 0.11- 0.21 eV, indicating their semiconducting behaviour. � 2024 World Researchers Associations.
