solids. The complex (Ph3P)2Rh(H)Cl(GeEt3) loses Et3GeH on reaction with carbon monoxide or ethylene; with hydrogen chloride triethylchlorogermane is formed. Excess of HGeCl3 and (Ph3P)3RhCl give the phosphonium salt, [Ph3PH]3[Rh(GeCl3)6], and similar salts are formed by the reaction between HGeCl3 and RhCl3 in acid solution, e.g. [Me3NH]3[RhCl3(GeCl3)3].
