Reactions of SiCl4 with R2PO(OH) (R=Me, Cl) yield compounds with six‐fold coordinated silicon atoms. Whereas R=Me afforded the hexacoordinated tetra‐cationic silicon complex [Si(Me2PO(OH))6]4+ with chloride counter‐ions, R=Cl caused release of HCl with formation of a cyclic dimeric silicon complex [Si(Cl2PO(OH))(Cl2PO2)3(μ‐Cl2PO2)]2 with bridging bidentate dichlorophosphates.
SiCl 4与R 2 PO(OH)(R = Me,Cl)的反应生成具有六倍配位硅原子的化合物。尽管R = Me提供了带有氯离子的六配位四阳离子硅络合物[Si(Me 2 PO(OH))6 ] 4+,但R = Cl却导致了HCl的释放并形成了环状二聚硅络合物[Si( CL 2 PO(OH))(CL 2 PO 2)3(μ-CL 2 PO 2)] 2具有桥接的二齿dichlorophosphates。
