| Summary: | A new bispyrazolylpyridine(BPP)-containing derivative, namely, 4-(3,5-dimethyl-1,7-diphenyl-1,7-dihydrodipyrazolo[3,4-b:4′,3′-e]pyridin-4-yl)phenol (1), C27H21N5O·2C2H6OS, has been synthesized by a Hantzsch multicomponent reaction using acetic acid (AcOH) as solvent and copper(II) acetate monohydrate [Cu(OAc)2·H2O] as mild oxidant. The structure of the compound was fully characterized by single-crystal X-ray diffraction. The crystallographic study shows that the molecule crystallizes in the triclinic system with space group P1, with one molecule per asymmetric unit. Whereas the phenolic substituent in the para position of the pyridine group is highly twisted from the planar bispyrazolopyridine core [56.19 (4)°], the two phenyl rings present on the nitrogen atoms are only slightly distorted [11.77 (5) and 29.17 (5)°]. The crystal structure is consolidated by intermolecular C—H...O hydrogen bonds and π–π stacking interactions. |
