Abstract
Crystals of 1,4-dichloro-7-methylpyrrolo[3,2-d]pyridazine,·C7H3N3Cl2, are monoclinic:a = 18.7465(9),b = 9.3031(3),c = 9.5363(3) Å, β = 104.755(3) °,Z = 8,P21/n,D x = 1.667 g cm−3, μ(MoKα) = 7.4 cm−1. The structure was solved by Fourier techniques and refined toR = 0.042 for the observed reflections, and 0.060 for all data measured. The two independent molecules in the asymmetric unit have similar geometry. The packing in the crystal is due to van der Waals' forces and two hydrogen interactions of type N-H ⋯ N.
