1,3-Diphenyltriazene is the organic compound with the formula PhN=N-N(H)Ph (Ph = C6H5). It is a prototypical triazene, i.e. a compound with the functional group RN=N-NR2. It is a pale yellow solid, prepared by the reaction of phenyldiazonium salts with aniline.[1] It is a planar molecule. The N-N distances are 1.287 and 1.337 Å.[2]
