5-[Acetamido(phenyl)methyl]-5-methylimidazolidine-2,4-dione.
The title compound, alternatively named N-[(4-methyl-2,5-dioxoimidazolidin-4-yl)(phenyl)methyl]acetamide, C(13)H(15)N(3)O(3), crystallizes in the centrosymmetric space group P2(1)/c with one molocule in the asymmetric unit. The imidazolidine-2,4-dione system is essentially planar, as evidenced by NMR studies. The dihedral angle between the planes of the imidazolidine and phenyl rings is 23.3 (1) degrees, while the dihedral angle between the acetamide side chain and the imidazolidine ring is 60.7 (1) degrees. The molecular structure and packing is stabilized by C-H.O and N-H.O interactions. Intermolecular hydrogen bonds form cyclic dimers, with graph-set descriptor R(2)(2)(8), and a chain of C(7).
