Crystal structure of 1-(2, 4-dimethyl-phenyl)urea

Abstract

In the title urea derivative, C 9 H 12 N 2 O, the dihedral angle between the benzene ring and the mean plane of the urea group, N - C(=O) - N, is 86.6 (1)°. In the crystal, the urea O atom is involved in three N - H⋯O hydrogen bonds. Molecules are linked via pairs of N - H⋯O hydrogen bonds, forming inversion dimers with an R 2 2 (8) ring motif. The dimers are linked by further N - H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (100).
