A semimicro method has been used to study the solubilities of the ternary system, Y(NO_3)_3·3H_2O-B15C5-CH_3CN, at 18℃. The results indicated that there is only one complex formed in this system. The stable complex has been isolated and its composition was determined by chemical analysis to be Y(NO_3)_3·B15C5·3H_2O and the dehydration behavior of the complex was studied using DTA and TG methods.
