Hydrogen-bonded bilayers in 7-benzyl-3-tert-butyl-1-phenyl-4,5,6,7-tetra­hydro-1H-spiro[pyrazolo­[3,4-b]pyridine-5,2'-indan]-1',3'-dione

Abstract: In the title compound, C31H29N3O2, the reduced pyridine ring adopts a conformation inter­mediate between the envelope and half-chair forms. The aryl rings of the benzyl and phenyl substituents are nearly parallel and overlap, indicative of an intra­molecular [pi]-[pi] stacking inter­action. A combination of two C-H...O hydrogen bonds and one C-H...N hydrogen bond links the mol­ecules into a bilayer having tert-butyl groups on both faces.

Formula: C31H29N3O2

Keywords: crystal structure; spiro compounds; hydrogen bonding.
