''N''-Benzoyl-''N′''-phenylurea is an organic compound with PhCONHCONHPh formula. It is benzoylurea derivative substituted with phenyl group on the opposite nitrogen atom. ==Structure and bonding==
Structure of ''N''-benzoyl-''N''′-phenylurea was first determined in 2010. Molecules in this compound are approximately flat and exhibit high charge delocalization. Within the molecule an intramolecular N−H⋅⋅⋅O hydrogen bond is present forming pseudoaromatic 6-membered ring. Additionally intermolecular N−H⋅⋅⋅O hydrogen bonds are also present combining two molecules into a centrosymmetric dimer (8-membered ring is formed). Carbonyl C=O bond distances are equal to ca. 1.23 Å, C−N distances are in range of 1.34 to 1.41 Å.
