Figure 2 Selected mol­ecular packing, viewed down the a axis, of the title compound illustrating the hydrogen bonded network. Urea mol­ecules (green) form an R22(8) motif (Etter, 1990) involving contact 1 (entry 1, Table 1) that propagates to form an infinite ribbon. DMA mol­ecules (shown in blues with rotational disorder) are hydrogen bonded via N-H⋯O contacts 2 (entry 2, Table 1) at the edges of the ribbon. Hydrogen bonds are shown as dashed lines and hydrogen atoms have been omitted for clarity. Symmetry codes: (a) −x, 1-y, 1-z; (b) [{1\over 2}]x, [{1\over 2}]y, 1 − z.
