title: Urea-N,N-dimethyl-acetamide (1/1).
abstract: Urea forms a 1:1 solvate with N,N-dimethyl-acetamide (DMA) [systematic name: diamino-methanal-N,N-dimethyl-acetamide (1/1), C(4)H(9)NO·CH(4)N(2)O] with both mol-ecules positioned on a twofold axis, giving rise to rotational disorder of the DMA mol-ecule. The mol-ecules display a layered structure in which urea mol-ecules form hydrogen-bonded ribbons bounded by mol-ecules of solvent.
