A hydrogen‐bonded dimer of 13‐hydroxy‐13‐[(triisopropyl­silyl)­ethynyl]penta­cen‐6(13H)‐one

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) Å and O—H⋯O = 173 (2)°]. Within each dimer, the penta­cene units are π‐stacked (the distance between the mean least‐squares planes of 22 C atoms is 3.60 Å).
