Self-assembly of silanetriols with 4,4′-bipyridine affords infinite columns of cofacially arranged π-stacks as evidenced by X-ray data. Variation of the silanetriol reveals a subtle balance between hydrogen bonding and π interactions, which, by proper choice of the substituent, may foster either dominant hydrogen bonding or dominant π interaction.
