✦ Synopsis
Á2C 9 H 6 SO 4 À ÁC 10 H 8 N 2 Á5H 2 O, the asymmetric unit contains two 8-hydroxyquinoline-5sulfonate (HQS) anions, two 4,4 H -bipyridinium ions, a neutral 4,4 H -bipyridine molecule and ®ve water molecules. The sulfonic acid group is deprotonated. Interestingly, in both the HQS anions, the OÐH bond is oriented away from the quinoline-N atom, since the water molecule competes in hydrogen bonding with the quinolinol-O atom. The neutral 4,4 H -bipyridine and one of the protonated 4,4 H -bipyridine moieties are bridged by two water molecules, resulting in a `U'-shaped hydrogen-bonded molecular arrangement. Many stacking interactions were observed between: (i) the pyridine rings of bipyridine moieties; (ii) the pyridine rings of bipyridine and HQS moieties; (iii) the pyridine ring of bipyridine and the benzene ring of the HQS anion.
