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-dicarbo-nitrile dimethyl sulfoxide disolvate

In the title compound, C16H11BrN6O center dot 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) angstrom, respectively] and their planes form a dihedral angle of 86.04 (5)degrees with each other. Intermolecular N-H center dot center dot center dot O, C-H center dot center dot center dot O and C-H center dot center dot center dot 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
