Hirshfeld surfaces and molecular fingerprint plots for the hemifumarate anion (a) and trimethoprim cation (b). Principal structural elements in the network (charge-assisted hydrogen bonds, π–π stacking and CH–π interactions) are shown on the two-dimensional fingerprint plot of each moiety in the unit cell.
