A central tunnel catches the eye in the symmetric arrangement of the adduct ( 1 · 2 ) 2 of 2‐aminobenzothiazole 1 , an analogue of a DNA base, and 1,3‐dimethyl‐2‐oxohexahy‐dropyrimidine ( 2 ) (on the right a view down the b axis). The adduct is dimeric; two molecules of 1 form a base pair, and each molecule of 1 is also bound to one molecule of 2 . The halves of the dimer are linked by hydrogen bonds, but each dimer is discrete.
