6'-Amino-3'-methyl-11H,2'H-spiro-[indeno-[1,2-b]quinoxaline-11,4'-pyrano[2,3-c]pyrazole]-5'-carbonitrile ethanol monosolvate.
In the title spiro-indeno-quinoxaline compound, C(22)H(14)N(6)O·C(2)H(6)O, the five-membered ring of the indene unit and the pyran ring are perpendicular [89.11 (3)°]. In the crystal, N-H⋯N hydrogen bonds connect the spiro-indeno-quinoxaline mol-ecules, and the ethanol solvent mol-ecules complete the hydrogen-bond network via O-H⋯N and N-H⋯O inter-actions.
