Diphenylsilanediol

Diphenylsilanediol, Ph₂Si(OH)₂, is a silanol. The tetrahedral molecule forms hydrogen-bonded columns in the solid state.^[4] It can be prepared by hydrolysis of diphenyldichlorosilane Ph₂SiCl₂. Diphenylsilanediol can act as an anticonvulsant, in a similar way to phenytoin.^[4] Although the compound is stable in normal conditions, the presence of basic impurities can accelerate the condensation of the silanol groups.
