π-Stacked chains in 3,5-dimethyl-1,7-diphenyl-1,7-dihydrodipyrazolo[3,4- b,4′,3′-e]pyridine

Abstract

The title compound, C21H17N5, was prepared using a microwave-induced condensation reaction between 5-amino-3-methyl-1- phenylpyrazole and formaldehyde. The molecules lie across twofold rotation axes in space group C2/c and are into chains by a π-π stacking interaction. © 2006 International Union of Crystallography. All rights reserved.
