New pyridine adducts of organosilanols

Gun'ko YK, Kessler VG, Reilly R


The reaction of Ph2Si(OH)(2)(1) with pyridine led to the formation of the pyridinium adduct (HO)Ph2SiOSiPh2O(PyH) (2). The complex contains one free silanol group and another silanol group is bonded to the amine via hydrogen bonding. The analogous reaction Of (c-C6H11)(7)Si7O9 (OH)(3) (3) with pyridine afforded the salt [PyH][{(c-C6H11)(7)Si7O9(OH)(2)}(2)H] (4). Both pyridinium derivatives have been characterised by X-ray diffraction. In complex 4 the anion consists of two silsesquioxane fragments connected by intermolecular hydrogen bonding.
