Synthesis and crystal structure of ()-2-(6-chloroimidazo[1,2-]pyridin-2-yl)-3-[4-(di-methyl-amino)phen-yl]acrylo-nitrile.

Abstract

The crystal structure of a compound incorporating a 6-chloroimidazo[1,2-a]pyridine unit linked to a dimethylaminophenyl-substituted acrylonitrile moiety was determined at 100 K. Within the crystal lattice, intermolecular C-H···N and C-H···Cl hydrogen bonds generate a network propagating along the [010] direction. C-H···π and π-π stacking interactions, together with additional intermolecular contacts, further stabilize the packing. Hirshfeld surface analysis quantified the relative contributions of key contacts: H···H at 30.2%, H···C/C···H at 28.6%, H···N/N···H at 19.9%, H···Cl/Cl···H at 12.2%, and C···C at 3.7%.
