Perylene (Per) was reacted with AsF5 dissolved in liquid SO2 to produce Per(AsF6)2. Far infrared absorption showed absorption by AsF6−. Nuclear magnetic resonance of 19F consisted of a quartet formed by indirect nuclear–nuclear coupling. The change of mass through the reaction indicated the formula Per(AsF6)2. Mass spectroscopy showed bonding between perylene and F and indicated no SO2 solvent in the sample. This solvent-free material does not conduct electrically. X-ray diffraction showed that the structure has an orthorhombic cell. Exposure to air changes the sample weight and colour, and results in conduction with semiconducting properties and reduced bonding between AsF6− and perylene.

N′-(4-Methoxybenzylidene)-5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide (3) was synthesized in a yield of 88% from an acid-catalyzed reaction of 5-methyl-1-phenyl-1H-1,2,3- triazole-4-carbohydrazide and 4-methoxybenzaldehyde in ethanol under reflux for 2.5 h. The structure of 3 was confirmed by the data obtained from infrared, nuclear magnetic resonance, mass spectroscopy, single crystal X-ray diffraction, and microanalysis.

Tautomerism of dibenzothiazolylmethane (1) and its C-methyl derivative (2) has been studied by 1H nuclear magnetic resonance, ultraviolet, and infrared spectroscopy using C,C-dimethyl (3) and N-methyl (4) derivatives as model compounds of the "CH" and "NH" forms, respectively. X-ray diffraction analysis of the "fixed" N-methyl derivative 4 shows that it corresponds to the Z-sE isomer 4b2. The CH tautomers are unstable in solution and they slowly isomerize into a mixture of NH tautomers that depends on the solvent and on the C-substituent (H or CH3).

Abstract Solid-state and solution 117Sn nuclear magnetic resonance studies of C2O4(SnPh3)2 have been carried out and found to be in good agreement with the tetrahedral environment of the tin (IV) atom as found from the solid state structure, previously determined by a single crystal X-ray diffraction analysis.
