title: Low-temperature redetermination of 1,3-bis-(penta-fluoro-phen-yl)triazene.
abstract: The crystal structure of the title compound, (C(6)F(5))(2)N(3)H, 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(6)F(5) 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).
