The title complex salt, (C8H20N)[ZnCl3(C3H7NO)], contains one [Et4N](+) cation (Et is ethyl) and one [ZnCl3(DMF)](-) anion (DMF is di-methyl-formamide). In the anion, the zinc atom is tetra-hedrally coordinated by a DMF ligand via the O atom and by three terminal Cl atoms. The average Zn-Cl bond length and Cl-Zn-Cl angle are 2.243 (11) Å and 114 (3)°, respectively.
