The trisilanol 1,3,5‐(HO i ‐Bu 2 Si) 3 C 6 H 3 ( 7 ), prepared in three steps from 1,3,5‐tribromobenzene via the intermediates 1,3,5‐(Hi‐Bu 2 Si) 3 C 6 H 3 ( 8 ) and 1,3,5‐(Cli‐Bu 2 Si) 3 C 6 H 3 ( 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 SiOH(H)Si and SiOH hydrogen bridges. Evidence was found for cooperative strengthening within the sequential hydrogen bonds.
