EFFECT OF ASCORBIC ACID AS REDUCING AGENT IN THE PREPARATION OF 1:1 CHLORO(L)Cu^I COMPLEXES(L:PYRIDINE QUINOLINE, ACRIDINE). A. Alemi, S. Shirinevare, Dept. of inorganic. Chem., Tabriz Univ. Tabriz-Iran

Some Cu^II L₂C1₂(L:Acridine, pyridine and other Heterocyclic Amines) complexes were prepared by Dubsky et co-worker(l) and also PETER et al (2) were studied some characters and structure of these type complexes. Investigation of the Reaction between ascorbic acid and copper(II) chlorid in the presence of some heterocylic amines (pyridine, quinoline, acridine) shows that, the product of reactions are in the form of CuICl L complexes, and also the reactions of CuIICl2L2 complexes with ascorbic acid shows the same product, as we were found previously. In this study we were used elementry analysis, IR, FT-IR, NMR, XRD and also conductivity and magnetic succeptibilty measurement of the products were examined. To summarize,the Role of ascorbic acid in two different reaction process is, no any ligand interaction with complexes. It should be noted that the action of ascorbic acid with Cu(II) complexe with transformation of then to Cu(I) complexe is a new method of Cu^I complexe preparation from Cu^II complexe without any ligand exchange.
