2-Isopropyl-6-methyl-4-oxo-3,4-dihydropyrimidin-1-ium 2-carboxy-4,6-dinitrophenolate monohydrate
In the title mol-ecular salt, C(8)H(13)N(2)O(+)·C(7)H(3)N(2)O(7) (-)·H(2)O, the pyrimidinium cation is essentially planar, with a maximum deviation of 0.009 (1) Å. The cation undergoes an enol-keto tautomerism during the crystallization. In the crystal, the ion pairs and water mol-ecules are connected via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming two-dimensional networks parallel to the bc...
متن کاملBis(2-amino-4-methyl-6-oxo-3,6-dihydropyrimidin-1-ium) sulfate monohydrate
In the title hydrated mol-ecular salt, 2C5H8N3O(+)·SO4 (2-)·H2O, the components are linked by N-H⋯Os and Ow-H⋯Os (s = sulphate, w = water) hydrogen bonds, generating a layer by a+b+c and 2a-b translations. The cations are arranged nearly in parallel and show displaced π-π stacking centroid-centroid distance = 4.661 (2) Å between adjacent layers.
متن کامل3-Amino-2-methyl-4-oxo-3,4-dihydroquinazolin-1-ium p-toluenesulfonate monohydrate
In the title hydrated mol-ecular salt, C(9)H(10)N(3)O(+)·C(7)H(7)O(3)S(-)·H(2)O, the cation is protonated at a quinazolinone N atom and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds and C-H⋯O, C-H⋯π and weak aromatic π-π stacking inter-actions [centroid-centroid separations = 3.8648 (12) and 3.9306 (13) Å] help to establi...
متن کاملCrystal structure of methyl 4-(4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate
The title hydrate, C13H14N2O4·H2O, crystallizes with two formula units in the asymmetric unit (Z' = 2). The dihedral angles between the planes of the tetra-hydro-pyrimidine ring and the 4-hy-droxy-phenyl ring and ester group are 86.78 (4) and 6.81 (6)°, respectively, for one mol-ecule and 89.35 (4) and 3.02 (4)° for the other. In the crystal, the organic mol-ecules form a dimer, linked by a pai...
متن کاملMethyl 4-(3-ethoxy-4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate
In the title compound, C(15)H(18)N(2)O(5)·H(2)O, the pyrimidine ring adopts a flattened-boat conformation. The eth-oxy group attached to the benzene ring is in an extended conformation. The oxopyrimidine mol-ecules are linked into centrosymmetric R(2) (2)(20) dimers by O-H⋯O hydrogen bonds. The dimers are linked by N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane...
