Germanium reaction with aqueous solution

In the present paper the reaction of some elemental and compound semiconductors with aqueous solutions will be considered in relation to their surface structure. The influence of their semiconducting nature will be discussed where it is of significance. This paper is based primarily on work on germanium and HI-V compounds performed at die Lincoln Laboratory of M. I. T. over the last few years. 

The binuclear germanium-capped clathrochelate [Fe2DA03(Ge(CF3)3)2] oximehydrazonate was obtained by a template condensation of the tetradentate H2DAO ligand with IGe(CF3)3 in an aqueous solution in the presence of CaCOs (Reaction 52). The resulting intramolecular macrobicyclic compound precipitated from the reaction mixture, and the equilibrium shift due to the formation of the solid allowed one to isolate this complex in a relatively high yield [73].

A determination of the heats of solution of germanium dioxide and tetrafluoride in aqueous hydrogen fluoride, to give the same final composition of fluorogermanic acid, when taken in conjunction with the precisely known heats of formation of the solids should also yield a precise value of Aif((HF(aq)) from the overall reaction heat of...
