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 ...
