Hydrogen-bonded chains in the crystal structures of (a) SQABPY-I [P21/n form; Cambridge Structural Database (CSD) refcode HAZFAP01; Martins et al., 2009BB40] and (b) SQABPY-II (C2/c form; CSD refcode HAZFAP07; Martins et al., 2009BB40), showing the differing protonation states (orange asterisks) and molecular torsions of bi­pyridine rings (green lines). Hydrogen bonds are drawn as dashed cyan lines.
