4-(Dimethyl­amino)pyridinium tribromide: whole mol­ecule disorder of cation and anion

In the title salt, C(7)H(11)N(2) (+)·Br(3) (−), the cation and the near-linear anion [Br—Br—Br = 179.41 (8)°] both show whole-mol­ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N—H⋯Br inter­action. The crystal studied was found to...

description In the title salt, C(7)H(11)N(2) (+)·Br(3) (−), the cation and the near-linear anion [Br—Br—Br = 179.41 (8)°] both show whole-mol­ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N—H⋯Br inter­action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%.
