X-RAY STRUCTURE OF TRICYCLOHEXYLMETHYL CHLORIDE

The X-ray crystallographic structure of tricyclohexylmethyl chloride, a precursor of the tricyclehexylmethyl radical, has been determined. C olourless tablets of C19H33Cl crystallized from hexane/chloroform in t he orthorhombic space group Pnma, with cell dimensions a 10.725(3), b = 15.670(3), c = 10.168(3) Angstrom; V = 1708.8(1.3) Angstrom(3): Z = 4. 1586 reflections with I > 3 sigma(I), and 302 with zero intensity, on refinement gave R = 0.046, R(w) = 0.076. The three cyclohexyl rings are arranged to give the molecule a plane of symmetry containing the central C-H axis. The large volume per nonhydrogen atom, of about 21.3 Angstrom(3), is close to values found in the crystal structures of an alogous tricyclohexyl compounds.
