%X The ~1H chemical shift of ZnCl_2 aqueous solution has been measured by N.M.R.The hydration number of Zn~(2+)cation,equal to 3.8,was determined accordingto semi-empirical relationship between ~1H chemical shift,temperature T and concen-tration of ZnCl_2.The compositions of coordination compounds which are formedin TBP-CCl_4 extracting ZnCl_2 were studied by ~1H and ~(13)C N M R,as ZnCl_2·2TBP·2H_2O and ZnCl_2·2TBP.The phenomena of N.M.R.proved that part of waterreally combined with ZnCl_2 to form coordination in ZnCl_2-TBP-CCl_4-H_2O system.
