Diphenylsilanediol Ph2Si(OH)2 is a silanol. The tetrahedral molecule forms hydrogen-bonded columns in the solid state. It can be prepared by hydrolysis of diphenyldichlorosilane Ph2SiCl2. Diphenylsilanediol can act as an anticonvulsant in a similar way to phenytoin. Although the compound is stable in normal conditions the presence of basic impurities can accelerate the condensation of the silanol groups.
