The title compound, N,N'-p-phenylenebis(4-methylbenzamide), C22H20N2O2
, crystallizes with an almost linear arrangement of the three benzene
units, but both outer benzene ring planes are twisted relative to the
plane of the central ring by 58.03 (6)degrees. N-H ... O=C hydrogen bo
nds perpendicular to the long axis of the molecules connect them into
ribbons parallel to the a axis.
