Crystal structure and Hirshfeld surface analysis of 3-(4-methoxyphenyl)-1-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine
(Int Union Crystallography, 2019)
In the title molecule, C19H16N4O, the planar pyrazolopyrimidine moiety is inclined to the attached phenyl rings by 35.42 (4) and 54.51 (6)degrees. In the crystal, adjacent molecules are linked into chains parallel to [110] ...
Crystal structure and Hirshfeld surface analysis of 4-(4-methylbenzyl)-6-phenylpyridazin-3(2H)-one
(Int Union Crystallography, 2019)
In this paper, we describe the synthesis of a new dihydro-2H-pyridazin-3-one derivative. The molecule, C18H16N2O, is not planar; the benzene and pyridazine rings are twisted with respect to each other, making a dihedral ...
Polymorphism of 2-(5-benzyl-6-oxo-3-phenyl-1,6-dihydropyridazin-1-yl)acetic acid with two monoclinic modifications: crystal structures and Hirshfeld surface analyses
(Int Union Crystallography, 2020)
Two polymorphs of the title compound, C19H16N2O3, were obtained from ethanolic (polymorph I) and methanolic solutions (polymorph II), respectively. Both polymorphs crystallize in the monoclinic system with four formula ...
Crystal structure and Hirshfeld surface analysis of hexyl 1-hexyl-2-oxo-1,2-dihydroquinoline-4-carboxylate
(Int Union Crystallography, 2020)
The asymmetric unit of the title compound, C22H31NO3, comprises of one molecule. The molecule is not planar, with the carboxylate ester group inclined by 33.47 (4)degrees to the heterocyclic ring. Individual molecules are ...
Crystal structure and Hirshfeld surface analysis of (Z)-6-[(2-hydroxy-5-nitroanilino)methylidene]-4-methylcyclohexa-2,4-dien-1-one
(Int Union Crystallography, 2019)
The title compound, C14H12N2O4, is a Schiff base that exists in the keto-enamine tautomeric form and adopts a Z configuration. The molecule is almost planar, the rings making a dihedral angle of 4.99 (7)degrees. The molecular ...
Crystal structure and Hirshfeld surface analysis of two 5,11-methanobenzo[g][1,2,4]triazolo[1,5 c][1,3,5]oxadiazocine derivatives
(Int Union Crystallography, 2019)
In the title compounds, 9-bromo-2,5-dimethyl-11,12-dihydro-5H-5,11-methanobenzo[g][1,2,4]triazolo[1,5-c][1,3,5]oxadiazocine,C13H13BrN4O(I),and 7-methoxy-5-methyl-2-(pyridin-4-yl)-11,12-dihydro-5H-5,11-methanobenzo[g][1,2,4] ...
Crystal structure and Hirshfeld surface analysis of (E)-2-(2,4,6-trimethylbenzylidene)-3,4-dihydronaphthalen-1(2H)-one
(Int Union Crystallography, 2019)
A novel chalcone, C20H20O, derived from benzylidenetetralone, was synthesized via Claissen-Schmidt condensation between tetralone and 2,4,6-trimethyl-benzaldehyde. In the crystal, molecules are linked by C-H center dot ...
Crystal structure and Hirshfeld surface analysis of N-{2-[(E)-(4-methylbenzylidene)amino]phenyl}-2-(5-methyl-1-H-pyrazol-3-yl)acetamide hemihydrate
(Int Union Crystallography, 2019)
The asymmetric unit of the title compound, C20H20N4O center dot 0.5H(2)O, contains two independent organic molecules (1 and 2) and a water molecule of crystallization. The two molecules differ primarily in the dihedral ...
Hirshfeld surface analysis and crystal structure of N-(2-methoxyphenyl)acetamide
(Int Union Crystallography, 2019)
The title compound, C9H11NO2, was obtained as unexpected product from the reaction of (4-{2-benzyloxy-5-[(E)-(3-chloro-4-methylphenyl)diazenyl]benzylidene}-2-phenyloxazol-5(4H)-one) with 2-methoxyaniline in the presence ...
Crystal structure and Hirshfeld surface analysis of (Z)-6-[(2-hydroxy-4-methylanilino)methylidene]-4-methylcyclohexa-2,4-dien-1-one
(Int Union Crystallography, 2019)
The title compound, C15H15NO2, is a Schiff base that exists in the keto-enamine tautomeric form and adopts a Z configuration. The molecule is almost planar, with the two phenyl rings twisted relative to each other by 9.60 ...
