Bis(2,6-dimethyl-pyridinium) dibromo-iodate bromide.

In the title salt, 2C7H10N+·IBr2−·Br−, each of the anions, viz. [IBr2]− and Br−, lie on a twofold axis. The IBr2− anion is almost linear, with a Br—I—Br angle of 178.25 (3)°. The cation is essentially planar (r.m.s. deviation = 0.0067 A). In the crystal, each Br− anion links two cations via N—H⋯Br⋯H—N hydrogen-bonding inter­actions.
