The existence of the trans effect of halogen cupric complexes

J. Gažo

Slovak Technical University, Bratislava

 

Abstract: The systems Cu++, Cl- and Br- in acetone, CuCl2 in acetone, and CuBr2 in acetone were studied by a spectrophotometric method. The complex ion CuCl3Br-- (I) forms in acetone. I changes with time and the velocity of this change increases with the increase of concn. of free Br-. The velocity of the reduction of Cu++ to Cu+ in halogen cupric complexes (II) in acetone decreases in the order CuI2, CuBr2, CuCl2 and is favorably affected by an unequal formation on the inner sphere of II. The results of these detns. favor the hypothesis of the existence of transeffect in II.
