The barbiturate salts 2-amino-1,3-dimethylimidazolium N,N’-dimethylbarbiturate (8) and 1,3- diisopropyl-4,5-dimethylimidazolium N,N’-dimethylbarbiturate (10) are obtained from N,N’- dimethylbarbituric acid (6) and 2-imino-1,3-dimethylimidazoline (7) or 2,3-dihydro-1,3-diisopropyl- 4,5-dimethylimidazol-2-ylidene (9) in good yields. Their crystal structures reveal the presence of strong interionic N-H-O (8) and C-H-O (10) hydrogen bonds to give dimeric (8) and monomeric (10) ion pairs. These pairs are linked by weak C-H-O hydrogen contacts to give three-dimensional networks.
