Abstract
The crystal structures of 2-chlorobenzophenone (1) and 2,5-dichlorobenzophenone (2) were obtained by single-crystal X-ray diffraction. Crystallization of 1 occurs in the centrosymmetric monoclinic space group P21/c (No. 14) with a = 8.2812(8), b = 16.5933(1), c = 7.7599(7); β = 98.488(5)° and Z = 4. Crystallization of 2 occurs in the centrosymmetric orthorhombic space group Pbca (No. 61) with a = 16.414(3), b = 7.7896(1), and c = 17.754(4); and Z = 8. Details of the structures and spectroscopic results are presented and discussed. Torsion angles about the carbonyl functionality were found to be outside the previously observed values for unsubstituted benzophenones by greater than 20°.
