Crystal structure and Hirshfeld surface analysis of 5-amino-5′-bromo-2′-oxo-2,3-di­hydro-1H-spiro­[imidazo[1,2-a]pyridine-7,3′-indoline]-6,8-dicarbo­nitrile dimethyl sulfoxide disolvate

In the title compound, C(16)H(11)BrN(6)O·2C(2)H(6)OS, 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—H⋯O, C—H⋯O and C—H⋯N 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.
