Abstract
4,4'-Diamino-3,3'-dimethylbiphenyl, C14H16N2, crystallizes with cell dimensions a=7.44, b=23-70, c = 6.47 A, space group P212121 and Z = 4. The structure has been determined from three-dimensional X-ray data and refined by the minimum-residual method, with isotropic temperature factors for individual atoms, to give a final R index of 11%. The two phenyl rings are not coplanar but are twisted around the linkage between them, C(1)-C(1'), so as to be mutually inclined at an angle of 41 °; in addition each phenyl ring is bent through an angle of about 3 ° away from the line C(1)-C(1'). The length of the bond C(1)-C(I') is 1.504 +0-013 A.
