摘要：

The structure of the title compound, C22H16N2O2 commonly called trans-N,N'-dimethylquinacridone, has been reinvestigated at 223 K [the original determination was by Zavodnik, Chetkina & Val'kova (1981). Zh. Struckt. Khim. 22, 188-190; and also by Ohmasa & Susse (1976). Naturwissenschaften, 63, 387-388]. The structure, in space group P2(1)/c, is basically in good agreement with those reported earlier, but is determined with higher precision. The entirely planar centrosymmetric molecules are arranged with major overlap of the acridine skeleton along the stacking axis.
