Quinuclidine betaine (1-carboxymethyl-1-azabicyclo[2.2.2]octane inner salt, QNB) forms a complex with p-hydroxybenzoic acid (HBA) at the 1:1 ratio. The crystals are triclinic, space group P 1, with two symmetry non-equivalent QNBÁHBA complexes linked by a sequence of four O-HÁÁÁO hydrogen bonds into
