Interaction of tantalum halides with lithium aluminum hydride in ether

Abstract

1. In the interaction of tantalum halides with lithium aluminum hydride, regardless of the ratio of the initial components, tantalum tetraaluminum hydride Ta(AlH4)4 is formed; during the reaction it already decomposes, eliminating aluminum hydride and forming products of variable composition TaHn(AlH4)4−n. 2. The solubility of tantalum and lithium chlorides at room temperature and that of their bromides in the interval −70 to +25° were determined. When tantalum pentabromide is treated with ether, it is reduced.
