4,5,6,8,9-Pentachloropyrimido[1,2-a][1,8]naphthyridin-10-one
Abstract
The title compound, C11H2Cl5N3O, crystallizes in the monoclinic system with two molecules in the asymmetric unit. The molecules are chemically identical but have different structural parameters. In the three-dimensional packing, the molecules are arranged in dimers that are connected by slipped pi-pi stacking, and these dimers are connected to one another through several C-H...O and Cl...Cl interactions.
