For the purpose of obtaining neostibosan, diethlyamine salt of p-aminophenylstibonic acid and that of antimonic acid was condensed and a new complex compound was obtained. This new compound was composed of 1mol. each of the tri-acid of p-aminophenylstibonic acid, antimonic acid and diethylamine, and contained almost the same quantity of antimony as that in neostibosan. The carbon content of this compound was 3% less than that in neostibosan but in other properties, the two compounds resembled one another. The toxicity of the new complex comdound was higher than that of neostibosan but the addition of glucose lowered its toxicity.
