(2,6-Dichlorophenyl)bis(2,4,6-trichlorophenyl)methyl radical (2) has been prepared through a reaction sequence of five stages obtaining four new intermediate compounds 1–4. Assignment of the structures of these compounds have been completely ascertained by means of their ¹H NMR spectra. The new persistent radical 2 has been characterized by EPR spectra and magnetic susceptibility measurements. The X-ray structural analysis of 2 shows that it adopts a propeller-like conformation with the phenyl rings twisted around their bonds to trivalent carbon. Magnetic susceptibility of 2 is characteristic of a paramagnet with a weak antiferromagnetic interaction at low temperatures (Weiss constant, Θ = −1.8 K).
