title: 2-Benzoyl-1,1-diethyl-3-phenyl-guanidine.
abstract: In the title tetrasubstituted guanidine, C(18)H(21)N(3)O, the guanidine and carbonyl groups are not coplanar, as reflected by the torsion angles involving the N=C atoms [17.6 (3), -141.68 (17) and 42.2 (3)°]. This is probably due to the absence of an intra-molecular N-H⋯O hydrogen bond, forming a six-membered ring, and is commonly observed in this class of compounds. In the crystal structure, centrosymmetric dimers are formed via pairs of inter-molecular N-H⋯O hydrogen bonds. The dihedral angles between the guanidine plane and the phenyl ring and benzoyl plane are38.06 (9) and 41.54 (7)°, respectively.
