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 کاملCrystal structure and Hirshfeld surface analysis of (E)-4-amino-N′-[1-(4-methylphenyl)ethylidene]benzohydrazide
The structure of the title Schiff base, C16H17N3O, displays a trans configuration with respect to the C=N double bond, with a dihedral angle of 14.98 (9)° between the benzene rings. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, giving sheets extending across the (001) plane. Hirshfeld surface analysis gave fingerprint plots showing enrichment ratios fo...
متن کاملCrystal structure and Hirshfeld surface analysis of 1-(4-chlorophenyl)-2-{[5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl]sulfanyl}ethanone
In the title compound, C16H10Cl2N2O2S, the dihedral angles formed by the chloro-substituted benzene rings with the central oxa-diazole ring are 6.54 (9) and 6.94 (8)°. In the crystal, C-H⋯N hydrogen bonding links the mol-ecules into undulating ribbons running parallel to the b axis. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are the H⋯C (1...
متن کاملZwitterionic 1-{(1E)-[(4-hydroxyphenyl)iminio]methyl}naphthalen-2-olate: crystal structure and Hirshfeld surface analysis
The title zwitterion, C17H13NO2 (systematic name: 1-{(1E)-[(4-hy-droxy-phen-yl)iminium-yl]meth-yl}naphthalen-2-olate), features an intra-molecular charge-assisted N+-H⋯O- hydrogen bond. A twist in the mol-ecule is evident around the N-C(hy-droxy-benzene) bond [C-N-C-C torsion angle = 39.42 (8)°] and is reflected in the dihedral angle of 39.42 (8)° formed between the aromatic regions of the mol-...
متن کاملCrystal structure of (Z)-3-benzyloxy-6-[(2-hydroxyanilino)methylidene]cyclohexa-2,4-dien-1-one
In the title compound, C20H17NO3, the methyl-idene-cyclo-hexa-2,4-dienone moiety is approximately planar [maximum deviation = 0.0615 (10) Å] and is oriented at diherdral angles of 69.60 (7) and 1.69 (9)° to the phenyl and hy-droxy-benzene rings, respectively. The amino group links with the carbonyl O atom via an intra-molecular N-H⋯O hydrogen bond, forming an S(6) ring motif. In the crystal, th...
