(E)-7-[(4-Nitro­phen­yl)diazen­yl]-3a-(p-tol­yl)-2,3,3a,4-tetra­hydro-1H-benzo[d]pyrrolo­[1,2-a]imidazol-1-one 0.58-dimethyl sulfoxide 0.42-aceto­nitrile solvate: crystal structure, Hirshfeld analysis and DFT estimation of the energy of inter­molecular inter­actions

In the crystal structure of the title compound, C(23)H(19)N(5)O(3)·0.58C(2)H(6)OS·0.42C(2)H(3)N, prepared by the azo coupling of the 4-nitro­phenyl­diazo­nium salt with 3a-(p-tol­yl)-2,3,3a,4-tetra­hydro-1H-benzo[d]pyrrolo­[1,2-a]imidazol-1-one, the azo mol­ecules are linked by N—H⋯O hydrogen bonds into chains along the a-axis direction, and by the π–π inter­action into [101] chains. The dimethyl sulfoxide and aceto­nitrile solvent mol­ecules occupy the same positions, with populations of 0.585 (3) and 0.415 (3), respectively. These mol­ecules take part in C—H⋯O(N) and C—H⋯π contacts. The energy of the π–π inter­actions was estimated using DFT calculations. The Hirshfeld mol­ecular surface analysis revealed the positions of the most important inter­molecular contacts, such as hydrogen bonds and π–π inter­actions.
