## Abstract An x‐ray structural study of the 1‐methylcytosine H^+^ complex reveals asymmetrically hydrogen‐bonded dimers which are further stacked such that the molecular overlaps are between charged and neutral bases. This study supports the assignment of the asymmetry in the interbase hydrogen bo
