Abstract

In the title mol­ecular salt, C6H16NO+·C10H4N5O9−·2H2O, which crystallizes as a dihydrate, O—H⋯O hydrogen bonds link the barbiturate anion, the ethanaminium cation and the water mol­ecules of crystallization. The dihedral angle between the rings in the anion is 43.71 (8)°. In the crystal, an R22(8) ring motif hydrogen-bonding pattern is also found involving inversion-related barbiturate rings with N—H⋯O hydrogen bonds. As a result of the various hydrogen bonds an infinite two-dimensional network, propagating in (10), is formed.
