Complexes of Cu(II), Ni(II), Co(II), and Ag(I) Metals with 1,4-Bis(3-Phenyl Triazenil) Benzene
New complexes of Cu(II), Ni(II), Co(II) and Ag(I) with 1,4-bis(3-phenyl triazenyl) benzene are obtained. Using the methods of IR, EPR, electron spectroscopy, and chemical and thermogravimetric analyses, the composition and structure of the obtained complexes are studied. Based on IR, EPR, electron spectroscopy, and chemical and thermogravimetric analyses, a square-pyramidal structure of the complexes is proposed. The unusual behavior of the temperature dependence of the electrical resistance of the silver complex is detected, namely, the presence of a maximum on the temperature dependence of the resistivity in the range of ~240 to 300 K.
