Аннотация: EPR measurements have been made to obtain the magnetic resonance parameters of cobalt, nickel, manganese, iron, zinc, magnesium, and molybdenum bidentate complexes of 3,6-dichloropicolinic acid (the active ingredient of the herbicide Lontrel) in the solid state and in solution. Upon dissolution in water under normal conditions, all of the complexes preserve the coordination environment of the central ion, thus existing in the undissociated state under native conditions. The broadening of the signals of water-dissolved samples at 300 K indicates partial pairing of electrons and the joining of two or more molecules into polymeric chains.
