The Crystal Structure of N -(5-Phenyl-1,3,4-oxadiazol-2-yl)- N′ -benzoyl Urea,a Novel Insect-growth Regulator †

Abstract

The crystal structure of N-(5-phenyl-1,3,4-oxadiazol-2-yl)-N′-benzoyl urea, C₁₆H₁₂N₄O₃, a novel insect-growth-regulator (IGR), has been established; the crystal structure belongs to the triclinic system with Z = 2, and the urea linkage is coplanar with intramolecular hydrogen bond formation, making the structure analogous to a four-ring compound.
