N-(3,4-Difluoro-phen-yl)-N'-(2,5-di-methoxy-phen-yl)urea
Abstract:
In the title compound, C(15)H(14)F(2)N(2)O(3), the dihedral angle between the benzene rings is 64.5 (1)°. One F atom is disordered over two meta positions, with occupancy factors of 0.72 and 0.28. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds involving two N-H and one C=O groups of the urea central fragment, leading to a supra-molecular chain along [011].
