title: 1-(4-Methoxy-phen-yl)imidazolidine-2,4-dione.
abstract: In the title compound, C(10)H(10)N(2)O(3), the dihedral angle between the benzene and imidazolidine rings is 6.0 (4)°, consistent with an essentially planar mol-ecule. In the crystal, inter-molecular N-H⋯O hydrogen bonding between centrosymmetrically related mol-ecules leads to loosely associated dimeric aggregates. These are connected into a three-dimensional network by C-H⋯O inter-actions, as well as π-π inter-actions [centroid-centroid distances = 3.705 (3) and 3.622 (3) Å] between the imidazolidine and benzene rings.
