  • N. P. Bednyagina
  • Yu. A. Rybakova


Nickel and copper complexes of asymmetric 1-(1′-alkylbenzoimidazolyl-2′)-3-methyl-5-arylformazans and symmetric 1, 5-di(1′-alkylbenzoimidazolyl-2′)-3-alkylformazans are prepared, and their absorption spectra in the visible region are measured. Some views regarding the structures of the complexes are considered.
