چکیده
In the crystal structure of the title compound, C(28)H(21)Cl(2)N, π-π inter-actions link pairs of mol-ecules into centrosymmetric dimers with a distance of 3.756 (3) Å between the centroids of the pyridine rings. Weak inter-molecular C-H⋯Cl hydrogen bonds further link these dimers into chains propagating along [01]. The pyridine ring forms dihedral angles of 21.52 (1) and 55.87 (2)°, respectively, with the phenyl ring and the 4-chlorophenyl ring.
