Polyol Metal Complexes. 35 [1] Diolato Silicate and Germanate Ions from Aqueous Solution Hydrated lithium salts of monoanionic bis(diolato)‐hydroxo complexes of silicon and germanium have been crystallized from alkaline aqueous solutions. The isotypic compounds Li[E(AnErytH –2 ) 2 (OH)] · H 2 O, E = Si ( 1 ) or Ge ( 2 ), AnErytH –2 = anhydroerythritol dianions, were obtained in the form of pseudomeroedric twins, a fact that may be traced back to orthorhombic pseudosymmetry of the monoclinic crystals. With potassium as the counterion, anhydrous crystals of K[Si(AnErytH –2 ) 2 (OH)] were grown by evaporating the solvent almost entirely from the aqueous mother liquors.
