Low-temperature redetermination of 1,3-bis(pentafluorophenyl)triazene

Abstract

The crystal structure of the title compound, (C6F 5)2N3H, is stabilized by N - H⋯N hydrogen bonding, forming centrosymmetric dimers organized in a herringbone motif. Important geometrical parameters are N - N = 1.272 (2) and 1.330 (2) Å and N - N - N = 112.56 (15)°. The dihedral angle between C 6F5 groups is 21.22 (9)°. The room temperature structure was reported by Leman et al. (1993). Inorg. Chem. 32, 4324-4336]. In the current determination, the data were collected to a higher θ angle, resulting in higher precision for the C - C bond lengths(0.001-0.005 versus 0.003 Å).
