With
H3PO2; NH3; HCl;
In
hydrogenchloride;
Ge(OH)2 is prepared by addn. of a slight excess of H3PO2 to an aq.-hydrochloric, half-concd. soln. of GeO2 at 90°C and addn. of NH3; the ppt. is washed and dried; the dry intermediate is dissolved in aq. HCl and an excess of CsCl-soln. added;; repeated recrystn. from aq. HCl; elem. anal.;
