Nature of Atrazine (2-Chloro-4-ethylamino-6- isopropylamino-s-triazine )-Copper Chloride Complex.

Abstract

Treatment of atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) with anhydrous copper chloride in methanol yields 1 : 1 complex. The infrared spectra and n.m.r. spectra do not suggest coordination of the nitrogen atoms of the side chain or C₃N₃ ring with the metal atom; instead a bond between the π-electrons of the C₃N₃ ring and the metal atom is indicated from the far IR spectra of this complex.
