N,N'-Bis(2-phenyl-ethyl)naphthalene-1,8:4,5-bis-(dicarboximide).

ABSTRACT: The title compound, C(30)H(22)N(2)O(4), is a derivative of the naphthalene-imide pigments that are characterized by significant overlap of the stacked mol-ecules. The mol-ecule has a centre of symmetry. Accordingly, the phenylethyl groups are arranged in a trans fashion across the skeleton. The phenyl rings are not parallel to the naphthalene-imide skeleton and are twisted in the same direction by 9.27?(7)°. The mol-ecules are, however, stacked with insignificant overlap along the stacking axis, as characterized by appreciable slide in the direction of either the short or the long mol-ecular axis, in marked contrast to the ordinary naphthalene-imide pigments.
