2-Diethylamino-6-methylpyrimidin-4(3H)-one

Abstract

The title compound, C9H15N3O, contains four molecules (A, B, C and D) in the asymmetric unit. In the crystal, the A+A and D+D pairs form inversion dimers linked by pairs of N—H...O hydrogen bonds. The B+C pairing is linked by the same bonds. The dimers are further linked by weak C—H...O interactions.
