© 2022 Naghiyev et al.In the title compound, C16H11BrN6O·2C2H6OS, the 1,2,3,7-tetrahydroimidazo[1,2-a]pyridine ring system and the oxindole moiety are both nearly planar [maximum deviations = 0.042 (2) and 0.115 (2) Å, respectively] and their planes form a dihedral angle of 86.04 (5)° with each other. Intermolecular N - HO, C - HO and C - HN hydrogen bonds link molecules in the crystal through the O atoms of the solvent molecules, generating a three-dimensional network. A Hirshfeld surface analysis was performed to further analyse the intermolecular interactions.
