© 2022 Naghiyev et al.In the title compound, C23H16N6O3, the central five-membered cyclopentene ring adopts an envelope conformation while the five-membered spiro 2,3-dihydro-1H-pyrrole rings exhibit twisted envelope and envelope conformations. One of the 1,3-dihydro-2H-indol-2-one units is in an axial position and the other is in a bisectional position. The methyl methanimidate unit is in an equatorial position. The crystal structure of the title compound is consolidated by intermolecular N-HN, N-HO and C-HO hydrogen bonds, forming a three dimensional network.
