Crystal structure and Hirshfeld surface analysis of methyl 4'-amino-3',5'-di-cyano-2,2''-dioxodi-spiro[indoline-3,1'-cyclo-pentane-2',3''-indolin]-3'-ene-5'-carboximidate with an unknown solvent.

In the title compound, C 23 H 16 N 6 O 3 , the central five-membered cyclo-pentene ring adopts an envelope conformation while the five-membered spiro 2,3-di-hydro-1 H -pyrrole rings exhibit twisted envelope and envelope conformations. One of the 1,3-di-hydro-2 H -indol-2-one units is in an axial position and the other is in a bis-ectional position. The methyl methanimidate unit is in an equatorial position. The crystal structure of the title compound is consolidated by inter-molecular N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, forming a three dimensional network.
