摘要：

The crystal structures of 4,4'-bis-(dimethylhydroxysilyl)biphenyl (1) and m-bis(dimethylhydroxysilyl)benzene (2) are reported. Crystals of (1) are monoclinic, P2(1)/n, with a 9.970(2), b 7.185(1), c 24.134(2) Angstrom, beta 98.795(8)degrees, and Z 4. Crystals of (2) are monoclinic, P2(1)/n, with a 5.960(1), b 24.205(10), c 18.635(9) Angstrom, beta 97.14(1)degrees, and Z 8. In compound 1, a combination of O-H ... O hydrogen bonds and C-H ...pi interactions results in the formation of sheets of enantiomeric pairs of helices, and these sheets are linked by additional C-H ...pi interactions into a continuous three-dimensional network. In compound 2 both O-H ... O hydrogen bonds and C-H ...pi interactions are also present but, in this case, hexagonal arrays of stacks of molecular dimers are formed. (C) 2000 Elsevier Science S.A.
