Comparison of the conformations of (a) the cIMP/IMP anions and (b) the His cations in L-His–cIMP (black; this work) and L-His–IMP·MeOH·H2O (grey) (Ślepokura & Petrus, 2010BB24; light orange in the electronic version of the paper). The common reference points are the labelled atoms. In IMP, the relative orientation of the hypoxanthine (Hyp) base and ester atom O5′ is stabilized by an intra­molecular C8—H8⋯O5′ hydrogen bond (dashed line).
