In the title salt, C14H14NO+·C24H20B−·C2H6OS, the cation is nearly planar and is totally disordered, each of the two positions being occupied equally. The crystal structure has an O—H
O hydrogen bond between the disordered cation and the dimethyl sulfoxide molecule. A C—Hπ interaction between the disordered cation and a phenyl ring of the tetraphenylborate anion is also present.

The principal molecule of the title molecule, C12H8ClN3O3·C3H7NO, is essentially planar. The two benzene rings make a dihedral angle of only 6.9 (1)°. The nitro group is slightly twisted with respect to the benzene ring to which it is attached [3.7 (1)°]. The dimethylformamide solvent molecule and the azobenzene molecule are linked through a strong O—HO hydrogen bond. In the crystal structure, the molecules are stacked through π–π interactions along [010]. Some weak C—HO interactions stabilize the packing.

In the cation of the title compound, C20H26N22+·2Cl-·CH4O, there is an approximate twofold rotation axis. All the four chiral centers are in the S configuration. All three six-membered rings in the central part of the cation adopt a boat conformation. Both chloride anions and the O atom in the solvent molecule form hydrogen bonds with the cation, resulting in a chain along [010].
