N,N-Diethyl-2-hy-droxy-ethanaminium 2,6-dioxo-5-(2,4,6-trinitro-phen-yl)-1,2,3,6-tetra-hydro-pyrimidin-4-olate dihydrate.

In the title mol-ecular salt, C(6)H(16)NO(+)·C(10)H(4)N(5)O(9) (-)·2H(2)O, which crystallizes as a dihydrate, O-H⋯O hydrogen bonds link the barbiturate anion, the ethanaminium cation and the water mol-ecules of crystallization. The dihedral angle between the rings in the anion is 43.71 (8)°. In the crystal, an R(2) (2)(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[Formula: see text]), is formed.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
