چکیده
The title compound, C25H24ClN3, comprises a 2-imino-pyridine ring fused with a cyclo-octane ring, which adopts a twist boat-chair conformation. In the crystal, C-H⋯N inter-actions form R 2 (2)(14) ring motifs and mol-ecules are further connected by weak C-H⋯π inter-actions. The resulting supra-molecular structure is a two-dimensional framework parallel to the ab plane.
