Abstract
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, C36H49 Br, (II), and 2'-iod o-2,2 " ,4,4 " ,6,6 " -hexaisopropyl-1,1':3',1 " -terphenyl, C36H49I, (III) , crystallize in space group Pnma. They are isomorphous and isostructural w ith a plane of symmetry through the centre of the molecule. The C-halide bo nd distances are 1.745 (3), 1.910 (4) and 2.102 (6) Angstrom for (I)-(III), respectively.
