摘要：

The trisilanol 1,3,5-(HOi-Bu2Si)(3)C6H3 (7), prepared in three steps from 1,3,5-tribromobenzene via the intermediates 1,3,,5-(Hi-Bu2Si)(3)C6H3 (8) and 1,3,5-(Cli-Bu2Si)(3)C6H3 (9) forms an equimolar complex with trans-bis(4-pyridyl)ethylene (bpe), 7-bpe, whose structure was investigated by V ray crystallography. The hydrogen-bonded network features a number of SiO-H center dot center dot center dot O(H)Si and SiO-H center dot center dot center dot N hydrogen bridges. Evidence was found for cooperative strengthening within the sequential hydrogen bonds. Copyright (c) 2007 John Wiley & Sons, Ltd.
