Electrocrystallization of three hydroxylated donor molecules derived from t
etrathiafulvalene (TTF) or ethylenedithiotetrathiafulvalene (EDT-TTF), ie.
Me3TTF-CH2OH, EDT-TTF(CH2OH)(2) and TTF(CH2OH)(4), in the presence of [n-Bu
4N+](2)[Mo6O19](2-) afforded 2: 1 cation radical salts, [donor(+.)](2)[Mo6O
19](2-), whose crystal structures have been solved by X-ray diffraction. In
the three different salts complex hydrogen bond networks develop in the so
lid state where the oxygen atoms of both the hydroxyl groups and the [Mo6O1
9](2-) anions act as hydrogen bond accepters. The observed hydrogen bonding
directed toward one surface, bridging oxygen atom of [Mo6O19](2-) is ratio
nalized by an analysis of ab initio calculations of the distribution of ele
ctrostatic potentials.
