✦ Synopsis

Ambiguity concerning the base structure of 6-oxoisocytidine methanol solvate {systematic name: 4-(R)-[4-amino-2,6-dioxopyrimidine-1-yl]-3(S)-hydroxy-2(R)-furanmethanol methanol solvate}, C 18 H 18 N 18 O 18 ÁCH 3 OH, is resolved by the crystal structure reported here. The 3-imine N site is protonated and forms a hydrogen bond with the 6-oxo carbonyl group of an adjacent molecule. The solid-state packing leads to the formation of sheets of molecules with the intervening space occupied by disordered methanol solvent molecules.
