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.
