description

The title compound, C14H8F2N2O2, also known as di(4-F-phen­yl)furazan N-oxide, was found as a side product in the synthesis of isoxazole derivatives. The are two molecules in the asymmetric unit. The bond length of the dipolar N—O unit is 1.107 (7) A. X-ray analysis confirmed the compound to have the desired structure
