Bis[3-(chloroacetyl)phenyl]diazene.

The title molecule, C14H8Cl2N2O2, is a trans-azobenzene which has a crystallographic inversion center at the mid-point of the N=N bond [N=N = 1.228 (4) Å]. There are neither hydrogen bonds nor π–π interactions between the aromatic rings, and the crystal structure is stabilized by van der Waals interactions. [ABSTRACT FROM AUTHOR]
