Crystal structure and Hirshfeld surface analysis of 3-(4-methoxyphenyl)-1-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine

Abstract

In the title molecule, C19H16N4O, the planar pyrazolopyrimidine moiety is inclined to the attached phenyl rings by 35.42 (4) and 54.51 (6)°. In the crystal, adjacent molecules are linked into chains parallel to [110] and [1\overline{1}0] by C—H...O and C—H...N hydrogen bonds. Additional C—H...π(ring) interactions lead to the formation of the final three-dimensional network structure. The Hirshfeld surface analysis of the title compound suggests that the most significant contributions to the crystal packing are from H...H (48.2%), C...H/H...C (23.9%) and N...H/H...N (17.4%) contacts.
