Abstract: The title salt, (C7H11N2)[FeCl4], consists of one essentially planar (the r.m.s. deviation for all non-H atoms being 0.004 Å) 4-(dimethylamino)pyridinium cation and a tetrahedral tetrachloridoferrate(III) anion. The cations and anions are arranged in layers parallel to (010). Besides electrostatic interactions, the crystal packing features N-HCl and C-HCl hydrogen bonds between cations and anions, forming a three-dimensional network.
