| Abstract: | In crystals of the silanols (Me3Si)3CSiPh(X)OH (X I or OMe) there is intermolecular π ⋯ HO bonding between a phenyl group in one molecule and an OH group in another, and there are probably intramolecular π ⋯ HO interactions in two silanols previously reported to show no hydrogen bonding. It is suggested that similar interactions should exist for OH groups attached to other metals or metalloids. |
