The whole molecule of the title compound, C14H8Cl2N4, is generated by inversion symmetry. The dihedral angle between the 2-chloro-phenyl ring and the tetra-zine ring is 47.65 (5)°. In the crystal, mol-ecules are linked by slipped parallel π-π inter-actions [centroid-centroid distance = 3.8199 (5), normal distance = 3.3127 (8), slippage 1.902 Å] forming columns along the a-axis direction.
Keywords: acaricide; clofentezine; crystal structure; π–π interactions.
