HYDROXYFLUODERYLLATES. PART IV. COMPLEX HYDROXYFLUOBERYLLATES AND HYDROXYFLUOBERYLLATES OF SILVER, THALLIUM AND HYDRAZINE

The hydroxyfluoberyllates of monovalent thallium, silver and hydrazine have been prepared and their properties studied. All these hydroxyfluoberyllates are excessively soluble in water. The silver and hydrazine salts are also soluble in 6o% alcohol. A solution of silver hydroxydnoberyllate, when boiled vigorously for a pretty long time, given an insoluble black precipitate of silver oxide-Thallium hydroxylinoberyllate is slightly deliquescent in nature. The solubilities of these compounds are greater than those of the corresponding sulphates or fluoberyllates.

The tetrammino complexes of Cu, Zn and Cd hydroxyfluoberyllatea as well as the hexammino complex of nickel hydronflooberyllate have been prepared. These compounds are stable only in an atmosphere of ammonia. Moist air decomposes them very quickly.
