X-Ray Crystal Structure Analysis of Novel 6-Amino-3-Phenyl-4-(Pyridin-4-yl)-2,4-Dihydropyrano[2,3-c]pyrazole-5-Carbonitrile.

The communication deals with the eco-friendly synthesis and X-ray crystal structure of an organic carbonitrile, namely 6-amino-3-phenyl-4-(pyridin-4-yl)-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile. The title compound was synthesized in 89% yield by following a simple, straightforward and highly efficient multicomponent one-pot protocol under the excellent catalytic influence of non-toxic trisodium citrate dihydrate under ambient conditions. X-ray diffraction studies reveal the packing of molecules in the crystal, which is strongly influenced by both intra and intermolecular hydrogen interactions. In addition, aromatic π–π interactions stabilize the molecular chains propagating along [001]. [ABSTRACT FROM AUTHOR]
