Crystal structure and Hirshfeld surface analysis of ethyl 2'-amino-5-bromo-3'-cyano-6'-methyl-2-oxo-spiro-[indoline-3,4'-pyran]-5'-carboxyl-ate
{{output}}
The crystal used for structure determination contained, along with the title compound, C17H14BrN3O4, an admixture [0.0324 (11)] of its 7-bromo isomer. The 2,3-di-hydro-1H-indole ring system is nearly planar, while the conformation of the 4H-pyran ring is close... ...
