Figure 5
A partial packing plot showing three hydrogen fumarate anions connected into a chain running horizontally (parallel to b) and the contacts of the central anion with ebastinium cations. Strong hydrogen bonds (O—H⋯O, N—H⋯O) are shown as thick dashed lines whereas weak C—H⋯O hydrogen bonds are shown as thin dashed lines. Pairs of R22(6) ring motifs illustrate how the weak C—H⋯O inter­actions augment the strong O—H⋯O hydrogen bond.
