COMPLEXES 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 were obtained. Using the methods of IR, EPR, electron spectroscopy, chemical and thermogravimetric analyzes, the composition and structure of the obtained complexes were studied. Based on IR, EPR, electron spectroscopy, chemical and thermogravimetric analyzes, a square-pyramidal structure of the complexes is proposed. The unusual behavior of the temperature dependence of the electrical resistance of the silver complex was detected, namely, the presence of a maximum on the temperature dependence of the resistivity in the range of ~240-300 K.
