摘要：

The reaction of BaO, SiO2, and an excess of ethylene glycol provides [Ba-Si(OCH2CH2O)3] . 3.25 HO(CH2)2OH, the first amazingly stable hexaalkylsilicate, in 90% yield. This complex was characterized by X-ray crystallography. The reactions with MgO and CaO give analogous compounds; with alkali metal oxides pentacoordinate silicates are formed.
