5‐(But‐3‐enyl)­pyridinium‐2‐carboxyl­ate–5‐butyl­pyridine‐2‐carboxyl­ic acid (1/1), a co‐crystal from Fusarium moniliforme

In the title co‐crystal, C10H11NO2·C10H13NO2, the carboxyl­ic acid moiety uses its acid H atom as the donor atom to bind strongly to the negatively charged O atom of the zwitterionic moiety [O⋯O = 2.557 (2) Å]. Meanwhile, the protonated N atom of the zwitterionic moiety forms a hydrogen bond with th...

Summary:In the title co‐crystal, C10H11NO2·C10H13NO2, the carboxyl­ic acid moiety uses its acid H atom as the donor atom to bind strongly to the negatively charged O atom of the zwitterionic moiety [O⋯O = 2.557 (2) Å]. Meanwhile, the protonated N atom of the zwitterionic moiety forms a hydrogen bond with the double‐bonded O atom of an adjacent zwitterionic moiety [N⋯O = 2.703 (2) Å] to give rise to a linear chain motif. The butenyl substituent (on the zwitterion) is disordered with respect to a butyl group and the butyl substituent (on the neutral mol­ecule) is disordered with respect to a butenyl group, the site occupancy for both being in an approximate 0.6:0.4 ratio.
