As for the cross-species coupling: "I don't think anyone expected it to happen".
Vonn confirmed the relationship around the same time on her Twitter and Facebook pages, acknowledging the frequent rumors about their coupling: I guess it wasn't a well-kept secret but yes, I am dating Tiger Woods.
Tapes of acid:base components are formed via coupling I; these tapes extend to form supramolecular sheets via O H⋯O and/or C H⋯O interactions.
Two previously reported co-crystals of Bipy with trimesic acid and 2,5-di-n-hexylterephthalic acid are also discussed, as well as a CSD search for coupling I in mono-and poly-carboxylic acid/Bipy complexes.
With tricarballylic acid, a co-crystal with stoichiometry 3 2 (acid:base) is generated, with a four-acid-four-base cyclic motif (involving coupling I) as the elementary supramolecular unit.
A coupling (I) involving O H⋯N and C H⋯O interactions, previously seen in co-crystals of carboxylic acids with other heterocyclic bases, is again shown to be involved in the formation of supramolecular structures.
