The sterically encumbered terphenyl halides 2′-chloro-2,2′′,4,4′′,6,6′′-hexaisopropyl-1,1′:3′,1′′-terphenyl, C36H49Cl, (I), 2′-bromo-2,2′′,4,4′′,6,6′′-hexaisopropyl-1,1′:3′,1′′-terphenyl, C36H49Br, (II), and 2′-iodo-2,2′′,4,4′′,6,6′′-hexaisopropyl-1,1′:3′,1′′-terphenyl, C36H49I, (III), crystallize in space group Pnma. They are isomorphous and isostructural with a plane of symmetry through the centre of the molecule. The C–halide bond distances are 1.745 (3), 1.910 (4) and 2.102 (6) Å for (I)–(III), respectively.
