X-ray diffraction structural data, a PPP quantum chemical calculation, and IR and UV spectral indices indicate that there is a six-membered chelate formazyl group with syn, s-cis configuration and strong intramolecular hydrogen bonding is characteristic for 1-p-anisyl-3,5-diphenylformazane. Spectroscopic criteria were established for this configuration of the formazane molecule. © 1988 Plenum Publishing Corporation.
