Abstract

AbstractThe trisilanol 1,3,5‐(HOi‐Bu2Si)3C6H3 (7), prepared in three steps from 1,3,5‐tribromobenzene via the intermediates 1,3,5‐(Hi‐Bu2Si)3C6H3 (8) and 1,3,5‐(Cli‐Bu2Si)3C6H3 (9) forms an equimolar complex with trans‐bis(4‐pyridyl)ethylene (bpe), 7·bpe, whose structure was investigated by X‐ray crystallography. The hydrogen‐bonded network features a number of SiOH(H)Si and SiOH hydrogen bridges. Evidence was found for cooperative strengthening within the sequential hydrogen bonds.
