Crystal structure and Hirshfeld surface analysis of 2-amino-4-methoxy-6-methylpyrimidinium 2-hydroxybenzoate
In the title mol-ecular salt, C6H10N3O+·C7H5O3-, the cation is protonated at the N atom lying between the amine and methyl substituents and the dihedral angle between the carboxyl group and its attached ring in the anion is 4.0 (2)°. The anion features an intra-molecular O-H⋯O hydrogen bond, which closes an S(6) ring. The cation and anion are linked by two N-H⋯O hydrogen bonds [R22(8) motif] to...
متن کاملZwitterionic 4-bromo-6-methoxy-2-{[tris(hydroxymethyl)methyl]iminiumylmethyl}phenolate: crystal structure and Hirshfeld surface analysis
In the solid state, the title compound, C12H16BrNO5 [systematic name: 4-bromo-2-((1E)-{[1,3-dihy-droxy-2-(hy-droxy-meth-yl)propan-2-yl]iminium-yl}meth-yl)-6-meth-oxy-benzen-1-olate], C12H16BrNO5, is found in the keto-amine tautomeric form, with an intra-molecular iminium-N-H⋯O(phenolate) hydrogen bond and an E conformation about the C=N bond. Both gauche (two) and anti relationships are found f...
متن کاملCrystal structure and Hirshfeld surface analysis of ethyl 2-{[4-ethyl-5-(quinolin-8-yloxymethyl)-4H-1,2,4-triazol-3-yl]sulfanyl}acetate
In the title compound, C18H20N4O3S, the 1,2,4-triazole ring is twisted with respect to the mean plane of quinoline moiety at 65.24 (4)°. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯N hydrogen bonds, forming the three-dimensional supra-molecular packing. π-π stacking between the quinoline ring systems of neighbouring mol-ecules is also observed, the centroid-to-centroid distance ...
متن کاملCrystal structure of ethyl (4R)-2-amino-7-hydroxy-4-phenyl-4H-chromene-3-carboxylate
In the title compound, C18H17NO4, the dihedral angle between the phenyl ring and the fused six-membered ring is 77.65 (4)°. The conformation of the mol-ecule is determined in part by an intra-molecular N-H⋯O hydrogen bond between the amino H atom and the carbonyl O atom, forming an S(6) motif. In the crystal, mol-ecules are linked into N-H⋯O hydrogen-bonded inversion dimers which are then conne...
متن کامل6-Methyl-2-oxo-N-(quinolin-6-yl)-2H-chromene-3-carboxamide: crystal structure and Hirshfeld surface analysis
The title coumarin derivative, C20H14N2O3, displays intra-molecular N-H⋯O and weak C-H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the mol-ecule [dihedral angle between the coumarin and quinoline ring systems = 6.08 (6)°]. The supra-molecular structures feature C-H⋯O hydrogen bonds and π-π inter-actions, as confirmed by Hirshfeld surface analyses.
