Crystal structure and Hirshfeld surface analysis of 6-amino-8-(2,6-dichlorophenyl)-1,3,4,8-tetrahydro-2H-pyrido[1,2-a]pyrimidine-7,9-dicarbonitrile

Farid N. Naghiyev et al.

Summary: The molecular structure of the title compound contains a 1,3,4,8-tetrahydro-2H-pyrido[1,2-a]pyrimidine ring, with the 1,4-dihydropyridine ring adopting a screw-boat conformation. In the crystal, intermolecular N-H and C-H hydrogen bonds form molecular sheets parallel to specific planes, while C-H...pi interactions link adjacent molecules into zigzag chains. Major contributions to the crystal packing come from N center dot center dot center dot H/H center dot center dot center dot N, H center dot center dot center dot H, C center dot center dot center dot H/H center dot center dot center dot C, and Cl center dot center dot center dot H/H center dot center dot center dot Cl contacts.
