title: A hydrogen-bonded dimer of 13-hydroxy-13-[(triisopropylsilyl)ethynyl]pentacen-6(13H)-one.
abstract: The title compound, C33H34O2Si, has been obtained as a product in the synthesis of 6,13-bis[(triisopropylsilyl)ethynyl]-6,13-dihydropentacene-6,13-diol. The solid-state structure reveals a dimer, with strong hydrogen bonds holding the two molecules in a face-to-face arrangement [O...O = 2.746 (2) A and O-H...O = 173 (2) degrees ]. Within each dimer, the pentacene units are pi-stacked (the distance between the mean least-squares planes of 22 C atoms is 3.60 A).
