Figure 1 The molecular structure of the title compound showing 50% probablility displacement ellipsoids. Hydrogen atoms have been omitted for clarity. A two-fold axis runs through C1, O2 of urea and O9, C7 of DMA, giving rise to the rotational disorder of the DMA molecule. Symmetry codes: (i) −x, y, − z. (ii) −x, y, 3/2-z. |
