Hexafluoroazomethane is decomposed by light of 2537 A to yield nitrogen, hexafluoroethane, perfluorotetramethyl hydrazine, and perfluorohexamethyl tetrazine. The relative amounts of the various products vary with the pressure: the compounds of higher molecular weight being produced more abundantly at higher pressures. A free radical mechanism is proposed for the reaction.

isomerizes rapidly to the trans isomer when exposed to daylight, but is stable in the dark. The compound has been characterized by NMR and UV spectra. Infrared and Raman spectra have been recorded and assigned with the assistance of a normalcoordinateanalysis. The molecular structure of cis-CF3NNCF3 has been determined by gas phase electron diffraction, and a planar CNNC skeleton, d(NN) 1.229(8) A

Reaction between pentafluorophenylazide and Ni(1,5-C8H12)2 affords green crystals of a tetra-azadiene complex Ni[(C6F5)2N4](1,5-C8H12). Cyclo-octa-1,5-diene is displaced by the ligands L = PPh3, PPh2Me, PPhMe2, or P(OMe)3 and L2= bipyridyl to form Ni[(C6F5)2N4]L2. 1H N.m.r. measurements on the bisdimethylphenylphosphine and bis(trimethyl phosphite) Complexes suggest two different modes of bonding
