(1) was synthesized according to the literature procedure (Badger et al. 1964) and recrystallized from absolute ethanol in the form of long orange needles.
Least squares
was carried out with SHELXL97 (Sheldrick, 2008) as implemented in WinGX (Farrugia, 1999). Hydrogen atoms were refined using a riding model the Uiso set to 1.2 times that of the heavy atom to which they are attached.Data collection: APEX2 (Bruker, 2011); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

(E)-1-(2-iodophenyl)-2-phenyldiazene (1) was synthesized by a literature procedure (Badger et al. 1964) and recrystallized from absolute ethanol. The molecule is planar with a trans arrangement of the phenyl groups around the N—N double bond. This double bond is rotated away from the iodine substiuent on C3 (Fig. 1). There are no strong intermolecular interactions, although π-stacking interactions may exist between the phenyl rings and the N—N double bonds (Fig. 2, 3).
